Tri-field EMF meter
Tri-field measures all three AC Electric Fields, Magnetic wave and Radio Microwave
AC gaussmeter, electric field meter, RF field strength meter combined in one electromagnetic instrument. The TriField Meter (and BroadBand TriField Meter) is an excellent tool for electricians or those curious about EMF fields.
The original TriField ? Meter combines all the features needed for fast, accurate measurements of electromagnetic fields. It independently measures electric field and magnetic field, and is properly scaled to indicate the full magnitude of currents produced by each type of field inside a conductive body. As a result, it "sees" much more than any other electromagnetic pollution meter. [en fran?ais]
Depending on where the knob is set, the meter detects either frequency- weighted magnetic fields (two separate scales), or frequency-weighted electric fields in the ELF and VLF range. It has significant sensitivity at 100,000 Hz, well past the 17,000 Hz horizontal scan of video displays. The radio/microwave setting can detect up to three billion Hz (3 GHz), which lets you gauge radio- wave power, CB and cellular phone equipment, and many types of radars.
This meter is the only one which combines magnetic, electric, and radio/microwave detectors in one package, so that the entire nonionizing electromagnetic spectrum is covered. In addition, the magnetic setting and the electric setting measure true magnitude, a feature found elsewhere only in more expensive meters. If you hold the meter in the center of a room and tip it to various angles, the magnetic reading will stay approximately the same regardless of which way you tip or rotate it. The electric reading is similar, although the presence of your body alters the actual electric field, so readings will vary more. The radio/microwave setting reads the full power of radiowaves when the meter is pointed toward the source.
Surprisingly, the standard TriField Meter is one of the least expensive meters available. The few other meters below $150 read only low-frequency magnetic fields and only in one direction (not true magnitude). The magnetic section of the TriField meter has three field-detecting coils pointing in the X, Y, and Z directions. A circuit amplifies these signals and gives them the proper frequency-weighting (sensitivity increases linearly from 30 Hz to 500 Hz, but with some residual sensitivity up to 100 MHz). A unique network combines the three coil outputs nonlinearly to approximate a true magnitude. The meter is sensitive from 0.2 to 100 milligauss full scale at 60 Hz (or 0.1 to 50 milligauss full scale at 120 Hz, etc.) with a resolution of 0.2 milligauss in the sensitive range. Accuracy is +/-20% at mid-range. A version with flat frequency response (instead of linear sensitivity increase) is also available for the same price.
The TriField Meter comes with a one-year warranty and a 9-volt transistor battery included. This type of battery lasts about 10 hours (total measurement time). When the BATTERY TEST reads low, the battery can be replaced with any rectangular 9 volt transistor or alkaline (which lasts about 50 hours) type. This meter is manufactured in the USA. TriField is a registered trademark of W.B. Lee.
USING THE TRIFIELD METER
A knob on the front has six positions: OFF, BATTERY TEST, two MAGNETIC field sensitivities (0.5-100 milligauss at 60 Hz, and 0.2-3 milligauss at 60 Hz, the second sensitivity to measure weak fields more accurately), ELECTRIC field and RADIO/MICROWAVE power density. The meter face is analog (needle type). A needle reading of one-third of full scale corresponds to either 3 milligauss (or 0.6 milligauss) @ 60 Hz, 3 kilovolts/meter @ 60 Hz, or 0.04 mW/cm2 respectively in the magnetic, electric, and radio/microwave field settings. Average magnetic field strength in North American homes and offices is 1-3 milligauss, so the meter is labeled "HIGH" above these levels.
MAGNETIC FIELD DETECTION
In most homes or offices, some areas are "hot" spots with readings in the HIGH range. Most often, this is caused by magnetic fields, which come largely from unpaired internal wiring. (Contrary to popular belief, power transmission lines and transformers do not generally contribute as much magnetic field as does internal wiring.) Other magnetic sources include video displays, motorized clocks and other equipment, electric blankets and heaters, fluorescent lights and light dimmers, and the transformers that are inside consumer devices. Much of the total field strength is from frequencies that are harmonics or multiples of 60 Hz (120 Hz, 180 Hz, etc.) and 17,000 Hz of video displays. Cars (especially near the front floorboard of electronic ignition cars) and motorcycles have fairly strong fields that are at frequencies higher than 60 Hz. Magnetic field is difficult to shield, but sheet steel is somewhat effective.
ELECTRIC FIELD DETECTION
A few areas in most homes read HIGH in the electric field setting. These include areas near improperly grounded equipment, the front of video screens, and fluorescent lights. Most of these fields can be easily shielded using a grounded metal screen or foil; VDT screens of this type are readily available. You can greatly reduce the strength of an electric field just by placing your hand in front of the source. This effect can be seen using a TriField meter.
MICROWAVE DETECTION
Occasionally, certain areas read HIGH in the radio/microwave setting. These include door seals around microwave ovens, and cellular phones (but not regular radio phones, which are very low-power). Radio/microwaves can be shielded in the same way as electric fields, although the lower frequency radio waves are not shielded by your hand as easily as microwaves are. (Metal screens will shield both.) In the United States, radars and FM transmitters can legally expose residents to moderately high power levels (as high as 10 mW/cm2 briefly or .57 mW/cm2 near cellular towers), but such exposure is not common.
REDUCING FIELD EXPOSURE
Some equipment is sensitive to magnetic fields (ie, a high resolution color monitor may not function properly above 30 milligauss). By seeing "hot" spots in your home and office, you can move equipment or furniture to reduce exposure. If a room has a "hot" spot, fields are generally much weaker elsewhere in that same room. |

UV Meter Card
With the depletion of the ozone layer, the number of skin C and
other health problems has risen dramatically, and the public is being
advised to avoid prolonged exposure to the sun. But on any given day,
how much exposure is too much, and how much SPF protection is enough?
The credit card sized UV Meter Card is designed
with a remarkable UV sensitive strip which changes from white to a
shade of purple when exposed to UV radiation for only 20 seconds.
Designed to react primarily to the wavelengths of lights between
290-325 nm, (the UV range) which are known to be the sunburn and skin
damaging rays. The stronger the radiation, the darker the shade of
purple. Simply compare on the adjacent color matching chart to see the
corresponding "likelihood of sunburn" warning. Guidelines printed right
on the meter card allow the user to determine the sun-screen SPA level
required under the prevailing conditions.
You can now take immediate measurements to
ensure that you are protecting the health of your family, friends, and
associates. The card will change back to its original color within
minutes and can be reused hundreds of times. Great for days at the
beach, camping, boating. outdoor sports, and perfect for anyone who
works outdoors. Ask your employer to make them standard issue.
Bonus: Each card comes with a "Lens Tester Spot" This second meter reacts to
wavelengths up to 400 nm (both UVA & UVB) and is used to test the UV protection of
eye wear, garments and fabric. |

Pocket Magnetometer
DC magnetic fields can develop in many steel or iron objects if they
have been exposed to magnetic fields, current, or friction. Even
structural members in homes and barns have become magnetized due to
stray voltage. This hand-held device detects residual magnetism in
steel parts quickly and accurately. Simply place the test edge near or
against the object being tested, and the needle gauge points to a
reading representing the magnetism in the object at that site as well
as polarity. Will also verify thoroughness of de-magnetizing. Check out
your car, bed frame, desk furniture or any other metal objects you
spend time with. Can also be used to check the strength of magnets.

Natural EM Meter
The Natural EM Meter detects radio/microwaves and changes
in extremely weak static (DC or "natural") electric and magnetic
fields. Using both a needle type meter and audible tone, it detects:
radio transmitters, geomagnetic storms, unusual magnetic solar
activity, electrical activity of thunderstorms, leaky microwave ovens,
magnetized rocks or bed frames, analog cellular phone EMF output, and
concealed surveillance bugs. Because it can sometimes detect the
electrical presence of a person, this versatile meter can even be used
in paranormal studies. Sensitive to changes in electric fields of as
little as 3 V/m with a full scale deflection at 1000 V/m. Will measure
magnetic field changes as small as 0.5% of the Earth's magnetic field
(2.5 mG) and as high as 100 microtesla (1000 mG). RF sensitive down to
0.01 mW/cm?, with a full needle deflection at 1 mW/cm? over the

AC Electric Field Meter
Providing RMS electric field strength
readings over the frequency range of 5 Hz to 2 kHz, this handy meter
does what no other meter in this price range can do. Two switchable
ranges. Range 1 offers 20 V/m accuracy from 20 to 300 volts/meter and
range 2 offers 0.1 kV/m accuracy from 0 to 10 kilovolts/meter. Simple
to use, just set the dial to the desired range and take readings.
Operates on a 9V battery which is included. Has a large analog display
and comes with a complete 1 year warrantee.
As with any E-field sensing instrument, you
will find that your readings are more accurate if you do not distort
the ambient field with the presence of your body. Simply placing the
meter on a stable (non-conductive) surface and backing away, or taping
the meter to a 2 - 3 foot stick will allow you to move your body far
enough out of the way to avoid distortion.

Tri-Field Extended Range Broadband Meter
This modified version of the standard Trifield Meter has the following advantages:
? The magnetic field sensor has enhanced sensitivity to frequencies below 50Hz
(for example, sensitivity at 5 Hz is 33 times greater than the regular Trifield meter)
? The RF sensor is frequency-flat over the extended range of 100 kHz - 2.5 GHz.
This fills the gap of 100 kHz - 50 MHz missed by the regular Trifield meter
(However sensitivity is shifted to a range of 0.026 - 260 mW/cm?)

Magcheck 95 Sensor
Single axis magnetic field sensor, can be used with any good digital
multimeter (for low scale accuracy, your DMM must have a 200 mV AC
setting or 0.1 mV resolution) which accepts a dual banana jack.
Produces 1 mV AC per mG up to 50 Gauss. Highly accurate over the range
of 25 - 3000 Hz. Two foot shielded cable with dual banana jack
included. Our most accurate probe. Calibrated to 5% accuracy, NIST
traceable. 1 year warranty (Digital Multimeter not included)
Bonus!
Use your computer with this probe to make an ELF/VLF spectrum analyzer (with optional free software)!
Connect this probe to your PC's microphone jack with cable listed below
to provide spectrum analysis of the output up to about 20 kHz. You can
even add the
Audio Amplifier
to boost weak
signals. This has to be the lowest cost way to get frequency
information about your magnetic fields. Explore the mixture of
frequencies commonly associated with common household sources,
demonstrate harmonics, even compare shielding effects at various
frequencies.

Electric Field Sensor
Antenna-type attachment for DMM which measures electric field in V/m
& kV/m. Because electric fields occur whenever a voltage difference
occurs, you can detect electric fields from appliances which are
plugged in even if they are switched off. Unit produces 1 mV per V/m
with 20% accuracy. Check outlets and electrical cords, especially in
the bedroom. This sensor will determine the effectiveness of your
electric shielding devices, and assist greatly in positioning your
furniture. You will need a DMM which accepts banana jacks with 3/4"
spacing. (DMM sold separately).

Body Voltage Sensor
An external electric field will induce an electric field within our
bodies. In this sense, our bodies act as antennas picking up fields
from electric blankets, alarm clocks, powerlines, and just about
everything connected to a source of electric power, whether it is
switched on or not. Delicate biological cellular processes (like brain
function and heart muscle contraction) operate on the scale of
microvolts to millivolts. Some experts warn against induced voltages of
20 mV or higher as they can theoretically interfere with the subtle
cellular activity. Simply touch this sensor with a finger and know
instantly what effect external fields are having inside your body
(where it counts!). Will help you detect irritating sources of electric
field which may not otherwise be obvious. (Digital Multimeter sold separately).

Zap Checker
At this price, you can't beat the Zap
Checker as a relative field strength meter. It has tremendous
sensitivity and very broad band. Most RF meters use a microwave diode
detector as a basis of their detection system. They work well at high
signal levels, but have limitations at lower signal levels. The Zap
Checker's innovative design uses several stages of RF amplification
before detection, thereby making it more like a broad-band receiver
than a field strength meter.
The useable bandwidth extends from 3 MHz to
more than 5 GHz, and can detect even weak transmissions from
surprisingly long distances, or pinpoint leakage in cables, locate
hidden transmitters, determine optimum placement of computer wireless
equipment, monitor radiation levels at the baby's crib, detect hidden
cameras, audio bugs, and more. Detects digital and analog signals.
A manually adjustable sensitivity control allows you to adjust the
gain. Zap Checker has fixed internal antennas. Detection is in
logarithmic or linear modes. Use the logarithmic mode for stronger
signals In linear mode, the Zap checker picks up the weakest signals
for full display.
The signal reading is either by analog meter or
illumination of colored LED's. The Zap Checker also has a switch
enabled silent vibrator mode for situations in which it is undesirable
to view the displays directly. Zap Checker uses two AA batteries (not
included) for more than 80 hours of use and weighs less than 5 oz.

and pinpoint RF bugs by sweeping from the center of the room. Ideal for
security applications involving the installation of wireless
surveillance and data transmitting apparatus, localizing RFI sources,
determining "hot" and "cold" spots in the RF domain, discovering
potential hacker-site locations, evaluating cell tower radiation
patterns, detecting cable leakage, and so much more. Easy to use too.

High Frequency Pollution Meter for Wiring
Don?t just take our word for it. You can now
check for this pollution yourself! A special meter has been developed
which can be plugged into an electrical outlet to determine the levels
of EMF high-frequency pollution in your home or office both before and
after using the HF EMPOR. Extremely easy to use and reliable.
This meter is designed to measure only the high
frequency noise which may exist in your electrical wiring. It contains
special filters which remove the normal 60 Hz signal for the readout.
The meter is very easy to use. Simply plug the
meter into an electric outlet. The meter works equally well on standard
outlets (2 prong, or 3-prong), and GFI outlets. It can also be used
with surge suppressors, power strips or extension cords.
The readout of the meter gives an indication of
how much high frequency noise is in the wiring at the outlet where the
meter is located. The higher the readout, the more high frequency
pollution. The readout is not calibrated, but is very useful for making
relative (comparison) measurements.
Ideally, the readout should be as low as
possible. It is generally agreed that readings should be below 50.
Notice that unplugging appliances may affect the reading.
When using the meter in conjunction with the
Graham-Stetzer Filters, plug the meter into the outlet first. Then add
Graham-Stetzer Filters to the same outlet and nearby outlets and watch
the reading decrease.
The use of a power strip to increase the number
of available outlets is useful when you need multiple Graham-Stetzer
Filters to reduce the reading to the desired level.
The meter is re-usable.

Ferrite Snap Board
Cables can act as an antenna, especially if they pass close to a strong
source of radiofrequency radiation. One study has suggested that if the
cable of a hands free mic passes near the phone's antenna, it can pick
up some radiation and transmit it to your ear. Our ferrite snap bead is
designed to reduce RF radiation in the cable. Made in 2 halves, you
simply press it around the wire at any convenient location. Couldn't be
simpler. It is small and lightweight enough to be almost unnoticable,
yet powerful enough (50 ohm impedence minimum) to control nasty
radiation. These are brand new, top quality industrial surplus, made by
TDK. Will accommodate wires up to 5 mm (? inch) in diameter. About 1
inch long, grey color. If you are concerned about RF radiation in
wiring, this is the answer.

Linear Hall Eeffect Sensor
These semiconductor chips are the heart of a DC magnetometer probe. When a DC magnetic field is applied, a voltage is produce which is proportional to the strength of the field. They also be used to make a very simple DC magnetometer… schematic included! It is possible to position 3 units orthogonally and link them in series to make a “3-axis” DC magnetic field sensor.
The Hall-effect integrated circuit included in each device includes a Hall sensing element, a linear amplifier, and a CMOS Class A output structure. Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.
High precision in output levels is obtained by internal gain and offset trim adjustments made during the manufacturing process.
These features make Linear Hall Effect Sensor ideal for use in position sensing systems, for both linear target motion and rotational target motion. They are well suited for industrial, hobby and educational applications over extended temperature ranges, from -40°C to 125°C.
A 3-pin ultramini SIP for through-hole mount. Lead (Pb) free, with 100% matte tin plated leadframe. These devices have a quiescent output voltage that is 50% of the supply voltage. Operating Voltage: 4.5 - 6 V. Typical Sensitivity: 1.3 mV/G |

Electrosmog Detector
A new, inexpensive hand-held device available to the consumer which can detect the pulsing emissions from wireless communications technologies (mobile phones, masts, DECT digital cordless phones, w/LAN’s, Wi-Fi, etc.) which are considered by scientists to be the cause of health effects among a significant minority of the population.
The Electrosmog Detector enables you to judge the relative levels of such pollution by listening to both the volume and quality of the sound. GSM, 3G, wLANS, DECT digital cordless phones etc all sound different and after a little practice are easy to identify.
The Electrosmog Detector enables you to ‘hear’ the electrosmog that exists all around you. The level and quality of the sound emitted is directly related to the type and intensity of man-made microwave radiation.
It is not an alarm, nor is it a warning device. It is an educational tool providing an awareness of your personal environment. Curved design fits comfortably in the hand and requires no technical knowledge to operate. The Electrosmog Detector is the first true consumer product in this category.
In a world where fast-growing wireless technology is ever-present, the Electrosmog Detector allows you to hear the digital pulsing of microwave frequency signals. These could be from
Digital cordless DECT phones
Mobile phones

Digital Hotspotter
The Digital Hotspotter provides information on signal availability and strength as well as essential network information, including ID, security status and channel for most 802.11 b/g Wi-Fi networks. Use it to determine if you are exposed to Wi-Fi radiation, the strength and direction of the source(s), and the number of channels.
Travelers, students and other roaming Wi-Fi users can use the Hotspotter to find available networks. Use the Hotspotter to determine where your home or office coverage extends, and where the optimal locations for use of the network are. Security The Hotspotter can be used to determine whether your home or office network is leaky. The device can detect whether your access point’s signal extends beyond your walls, and whether it is secured. The Hotspotter can also help you detect rogue access points.
The Hotspotter displays an image of one to four vertical bars, indicating the relative strength of the signals detected by the Hotspotter. By scanning repeatedly, you may be able to determine whether you are moving closer to or farther from a network access point by watching the increase or decrease in the relative signal strength.
The Hotspotter scans 13 channels. While only 11 channels are used in the US, 13 channels are used for Wi-Fi in Europe. Channel information can be useful in detecting potential reasons for interference. Most access points are set to channel 1, 6 or 11 by default. If you see more than one network on the same channel, it is likely that you may experience problems with interference. In fact, Wi-Fi channels overlap on adjacent channels, and may cause interference on adjacent channels. You may wish to use the Hotspotter when configuring your home or office network to determine what channels are least likely to experience interference.
LCD screen displays information about multiple networks:
Network ID (SSID)
Signal strength
Encryption status (WEP and WPA)

Geomagnetometer with Portable Oscilloscope
Geomagnetometer
Analyzing frequency information from ultra-low frequency magnetic fields can be extremely challenging. Air coil type magnetic field probes just don't have the necessary sensitivity below about 20 Hz.
The voltage output from our Geomagnetometer (read more) provides excellent frequency information from low frequency signals. The amplified, unrectified, Hall effect probe output retains all the frequency information from the magnetic field under investigation.
Simply connect the voltage output from the Geomagnetometer to the oscilloscope or spectrum analyzer and monitor both field strength AND waveform, frequency, and spectrum distribution of your signals. Because the Geomagnetometer output produces 200 mV at full scale, you get plenty of signal to the oscilloscope or spectrum analyzer.
For example, on the 0-2 mG range: 2 mG produces 200 mV output, .05 mG produces 5 mV. On the 0-200 mG range: 200 mG produces 200 mV output, 5 mG produces 5 mV.
In our tests, the actual output range from the Geomagnetomer extends significantly beyond 200 mV, and was useful up to 60 Hz and beyond. Interested in .01 Hz? 2 Hz? 7.8 Hz? No problem! You can analyze fluctuations in the Earth's magnetic field, fields from audio recordings, and almost any other ultra-low frequency magnetic field source. Possibly biologic and paranormal sources?
Portable Oscilloscope
Anyone familiar with the operation of an oscilloscope will appreciate the incredible low price and full features of the hand held oscilloscope. Connected to a probe (magnetic, electric or RF) you can measure voltage up to 80V AC or DC and check the waveform up to 2MHz. See spikes, RF noise, harmonics. Check for dirty power. Operates on 5 AA batteries, not included. BNC input. Extend the input range to 600V with x10 probe setting.
* Input Impedence: 1Mohm//20pF (standard probe)
* Timebase Range: 0.2 micro-s to 1 hour/div
* Sensitivity: 5mV/div to 20V/div (0.1 mV minimum sensitity) |

Powerline Noise Finder
Handheld meter enables you to track the source of local transmission line high frequency noises. It also ferrets out residential and industrial noise sources, the type of noise that comes from power cables and power lines. It will also find other noise that may be coming from motors, battery chargers and thermostats. Lets you walk or drive around your home or neighborhood to search out leaky insulators, loose hardware and corroded ground lines quickly. You can track the noise source right down to the pole, transformer or insulator. You can also pinpoint faulty dimmers, electric fence arcs, sparking power equipment, neon signs and much more! Let equipment owners hear how troublesome their noise is and see first hand what's causing the problem.
This is a sensitive superhet AM receiver with a semi-log noise field strength meter for wide signal range and better resolution at the low end. A telescopic, direction-finding dipole antenna is balun isolated and optimized. This gives you a sharp, clearly defined null for accurately pinpointing noise sources quickly and easily.
It operates in the 135 MHz region where radiation from corona and arcing is far more localized. 0.3 uV sensitivity and wide-range AGC give you an ultra wide range noise level meter - over 70dB!
Bonus! Included headphone enables user to actually hear the noise you're tracking when you carry out the initial search. Then when you get close, observe the meter reading for the final location. Or plug-in a tape recorder! With your tape, your power company may figure out what's causing the noise and know how to fix the problem before they even come out. If you've done most of the detective work, they may be more likely to cooperate. Compact size. Needs one 9V battery. Size: 72 x 100 x 40mm Weight: 225g |

High-Frequency ElectroMagnetic Pollution Remover
Do you suffer from symptoms of electrical sensitivity such as headaches, tiredness, poor short term memory, fatigue, depression, nausea, rashes, irritability, or even chronic fatigue syndrome? High-frequency EMF pollution that is carried in wiring has been shown to be the source of electrical sensitivity symptoms for some people. This high-frequency EMF pollution is produced by common household items such as electric motors (found in hair-dryers, blenders, can openers, etc), loose wires, fluorescent lights, transformers, and especially dimmer switches.
The High-Frequency EM Pollution Reducer (HF EMPOR, also known as the Graham-Stetzer Filters) designed by Dr. Martin Graham, Professor Emeritus at the Electronics Research Laboratory of the University of California, Berkeley, consists of 20 EMF high frequency suppressors which are simply plugged into ordinary electric outlets, distributed throughout the home or office. These suppressors will measurably reduce the high frequency EMF pollution in your environment. A number of people have reported immediate relief from electrical sensitivity symptoms with the use of the HF EMPOR.
The suppressors do not use electricity, so they will not affect your utility bill, nor will they interfere with any computers, TV's. or other appliances. Installation is simple and enables you to avoid expensive electrician service calls. The suppressors are portable, so you can move them from one site to another. This is NOT a bio-energetic device. Special electronic circuitry simply drains the high-frequency pollution out of the wiring system.
This kit (20 units) will effectively filter an average size home or office. If you have a large home or office, or a large number of EMF high-frequency pollution producers, you may need additional EMF high-frequency noise suppressors. Specify North-American or European plug styles. |

SensorPlug
How would you like to turn on lights, cameras, fans, appliances, signs, radios, Holiday lights, fountains, alarms, gags, decorations, stun guns (or just about any other electrical device) simply by walking into the room? And have them shut off automatically when you walk out too?! Just plug SensorPlug into a wall outlet , then plug the device of your choice into the SensorPlug.
Use SensorPlug to economically light a dark hallway or basement/attic, or notify you about an intruder. Use it to save utility money by only activating devices when someone is in the room to enjoy them. Why have all those AC/DC converters drawing power (and emitting EMF) 24/7 when you only need them while you are using the device they power? Plug them into SensorPlug and save! Even use it to control lights in the bathroom eliminating the spread of germs from touching the light switch.
And get this, you can choose to have SensorPlug work only when lighting is dark (In the "L" position, whatever is plugged into the SensorPlug's outlet will turn ON when motion is detected and the ambient light level is low.) Or, in the "O" position, the Sensor Plug's outlet is energized whenever motion is detected regardless of the ambient light level.
In addition, you can adjust the length of time that the device will remain energized after motion is stopped (from 2 to 6 minutes).
Very simple to use. No wiring - No batteries - No tools. SensorPlug is like having an extra pair of hands when you need them. It lights up your way when you are carrying a laundry basket around the house, or you come home with bags of grocery in your hands, or with your child in one hand and a diaper bag in the other hand. It provides safety, security and convenience at an affordable price. SensorPlug comes complete with a spare fuse and screw for securing to the wall plate, if desired.
- Detection angle 160 degrees; Detects up to 25 ft.
- UL Listed To U.S. & Canadian Safety Standards
- Low power consumption (0.3A standby with induction)
- Circuit protected by easy to replace fuse (spare fuse included).
Use with products having an electrical rating of less than 500 Watts and Voltage Rating of 110-120 VAC, 60Hz AC. (Indoor Use Only). Patented, and carries 1 year mfr warranty. |

Degaussing Coil
Want to remove the magnetic fields from your bedsprings and steel belts in tires? How about steel pipes, barn framing, or desks? Want to degauss your TV, computer monitor or erase magnetic media like credit card strips, diskettes and audio tapes? This degaussing coil can do all that and more!
To demagnetize something ferroelectromagnetic you expose it to a strong AC magnetic field that slowly decreases. The idea is to magnetize the object completely in one direction, then slightly less in the opposite direction, then repeat with ever smaller decrements until only a very small residual magnetic field remains. Simply plug in this degaussing coil and hold it near the object you wish to treat. Then slowly back away until your are about 3 –4 feet away from the object. It's that simple!
Be careful when you handle this demagnetizer, don't leave it on more than absolutely necessary, and do not expose yourself unnecessarily. The magnetic field emitted can be well into the 17 Gauss range.
Re-check regularly, about every six months to a year, as degaussing may need to be repeated. A full 6" in diameter coil with momentary on/off switch (style may differ slightly from picture). 115VAC, UL approved. Made in USA. |

Tri-field Flat Frequency Response EMF meter
This modified version of the standard Trifield Meter has all the same specifications with this one important difference: magnetic field response is NOT frequency weighted. No need to specify 50 or 60 Hz calibration.
Tri-field measures all three AC Electric Fields, Magnetic wave and Radio Microwave
AC gaussmeter, electric field meter, RF field strength meter combined in one electromagnetic instrument. The TriField Meter (and BroadBand TriField Meter) is an excellent tool for electricians or those curious about EMF fields.
The original TriField ? Meter combines all the features needed for fast, accurate measurements of electromagnetic fields. It independently measures electric field and magnetic field, and is properly scaled to indicate the full magnitude of currents produced by each type of field inside a conductive body. As a result, it "sees" much more than any other electromagnetic pollution meter. [en fran?ais]
Depending on where the knob is set, the meter detects either frequency- weighted magnetic fields (two separate scales), or frequency-weighted electric fields in the ELF and VLF range. It has significant sensitivity at 100,000 Hz, well past the 17,000 Hz horizontal scan of video displays. The radio/microwave setting can detect up to three billion Hz (3 GHz), which lets you gauge radio- wave power, CB and cellular phone equipment, and many types of radars.
This meter is the only one which combines magnetic, electric, and radio/microwave detectors in one package, so that the entire nonionizing electromagnetic spectrum is covered. In addition, the magnetic setting and the electric setting measure true magnitude, a feature found elsewhere only in more expensive meters. If you hold the meter in the center of a room and tip it to various angles, the magnetic reading will stay approximately the same regardless of which way you tip or rotate it. The electric reading is similar, although the presence of your body alters the actual electric field, so readings will vary more. The radio/microwave setting reads the full power of radiowaves when the meter is pointed toward the source.
Surprisingly, the standard TriField Meter is one of the least expensive meters available. The few other meters below $150 read only low-frequency magnetic fields and only in one direction (not true magnitude). The magnetic section of the TriField meter has three field-detecting coils pointing in the X, Y, and Z directions. A circuit amplifies these signals and gives them the proper frequency-weighting (sensitivity increases linearly from 30 Hz to 500 Hz, but with some residual sensitivity up to 100 MHz). A unique network combines the three coil outputs nonlinearly to approximate a true magnitude. The meter is sensitive from 0.2 to 100 milligauss full scale at 60 Hz (or 0.1 to 50 milligauss full scale at 120 Hz, etc.) with a resolution of 0.2 milligauss in the sensitive range. Accuracy is +/-20% at mid-range. A version with flat frequency response (instead of linear sensitivity increase) is also available for the same price.
The TriField Meter comes with a one-year warranty and a 9-volt transistor battery included. This type of battery lasts about 10 hours (total measurement time). When the BATTERY TEST reads low, the battery can be replaced with any rectangular 9 volt transistor or alkaline (which lasts about 50 hours) type. This meter is manufactured in the USA. TriField is a registered trademark of W.B. Lee.
USING THE TRIFIELD METER
A knob on the front has six positions: OFF, BATTERY TEST, two MAGNETIC field sensitivities (0.5-100 milligauss at 60 Hz, and 0.2-3 milligauss at 60 Hz, the second sensitivity to measure weak fields more accurately), ELECTRIC field and RADIO/MICROWAVE power density. The meter face is analog (needle type). A needle reading of one-third of full scale corresponds to either 3 milligauss (or 0.6 milligauss) @ 60 Hz, 3 kilovolts/meter @ 60 Hz, or 0.04 mW/cm2 respectively in the magnetic, electric, and radio/microwave field settings. Average magnetic field strength in North American homes and offices is 1-3 milligauss, so the meter is labeled "HIGH" above these levels.
MAGNETIC FIELD DETECTION
In most homes or offices, some areas are "hot" spots with readings in the HIGH range. Most often, this is caused by magnetic fields, which come largely from unpaired internal wiring. (Contrary to popular belief, power transmission lines and transformers do not generally contribute as much magnetic field as does internal wiring.) Other magnetic sources include video displays, motorized clocks and other equipment, electric blankets and heaters, fluorescent lights and light dimmers, and the transformers that are inside consumer devices. Much of the total field strength is from frequencies that are harmonics or multiples of 60 Hz (120 Hz, 180 Hz, etc.) and 17,000 Hz of video displays. Cars (especially near the front floorboard of electronic ignition cars) and motorcycles have fairly strong fields that are at frequencies higher than 60 Hz. Magnetic field is difficult to shield, but sheet steel is somewhat effective.
ELECTRIC FIELD DETECTION
A few areas in most homes read HIGH in the electric field setting. These include areas near improperly grounded equipment, the front of video screens, and fluorescent lights. Most of these fields can be easily shielded using a grounded metal screen or foil; VDT screens of this type are readily available. You can greatly reduce the strength of an electric field just by placing your hand in front of the source. This effect can be seen using a TriField meter.
MICROWAVE DETECTION
Occasionally, certain areas read HIGH in the radio/microwave setting. These include door seals around microwave ovens, and cellular phones (but not regular radio phones, which are very low-power). Radio/microwaves can be shielded in the same way as electric fields, although the lower frequency radio waves are not shielded by your hand as easily as microwaves are. (Metal screens will shield both.) In the United States, radars and FM transmitters can legally expose residents to moderately high power levels (as high as 10 mW/cm2 briefly or .57 mW/cm2 near cellular towers), but such exposure is not common.
REDUCING FIELD EXPOSURE
Some equipment is sensitive to magnetic fields (ie, a high resolution color monitor may not function properly above 30 milligauss). By seeing "hot" spots in your home and office, you can move equipment or furniture to reduce exposure. If a room has a "hot" spot, fields are generally much weaker elsewhere in that same room. |

EMDEX Mate
The EMDEX Mate is a cumulative exposure meter which provides reliable 3-axis results that are displayed at the end of the measurement session. You see:
Time-Weighted-Average (this is the average level of exposure during the measurement period), Minimum and Maximum levels recorded during the measurement period, Standard Deviation, Percent of Time in Six Different Exposure Level Ranges, Cumulative Exposure Time
This instrument extends the capability of all investigators to perform exposure assessment studies for workers (during entire work periods or for individual tasks), home owners, children, and for all others where magnetic field exposure is to be evaluated. 0.1-1000 mG range with typical 3% accuracy at 50/60 Hz. Covers 40-1000 Hz.
Very simple to operate. Once the power switch has been turned on, data collection is initiated by setting a second switch to RUN. The Mate displays current real-time magnetic field levels every 0.5 seconds as it accumulates exposure data (however, individual measurement values are not recorded). To end data collection and view dosimetry results, set the second switch to DISPLAY RESULTS. The Mate continuously scrolls the statistical exposure measurement results until power is turned off. 50 hours operation with alkaline 9V battery. Includes NIST Traceable serialized calibration certificate. |

AC Sensor
In situations where you may not know if a wire is live, it would be nice to have a warning before you make a dangerous contact. The AC Sensor is a hand-held device for determining the presence or absence of 50-600 volts AC in insulated wires, wall receptacles, fuses, junction boxes, switches and other voltage-carrying electrical systems. The AC Sensor determines defective grounds, reverse polarity, and induced voltage. It is not necessary to disconnect the system in question because no contact is required for operation and current flow is not necessary to locate voltage. Simply touch the plastic tip to a connection point or move it along a wire. If AC voltage is present, the tip will glow red and you will hear an audible tone. The audio alert reacts only to an AC voltage field, and will not beep when it comes in contact with a static field. There is no ON/OFF switch on the AC Sensor. Switches can wear out over time or even malfunction. Because the AC Sensor has no switch it is always ready to use! Suitable for indoor or outdoor use. Great for electricians, emergency responders, handymen, and hobbyists. CE, UL listed and manufactured 100% in the U.S.A. Uses 2AAA batteries, included. |

Nardalert XT
Accuracy: The Nardalert XT is very accurate when worn on the body over effectively the entire RF spectrum (100 kHz to 100 GHz) with all types of signal formats. Nothing else comes close to matching its bandwidth even on paper. The specified bandwidth for some models is for use off the body, which is of little value as a personal monitor. Other models tend to "false alarm" a great deal. RF Safety Solutions has used the Nardalert XT at all types of complex sites and have been amazed how well it matches up with the best survey instruments.
bullet
Alarms and Indicators: The Nardalert XT has two very distinct audible alarms that can be set using the optional interface kit. Both alarms are quite loud. It is often difficult to hear the other monitors that are on the market, including the earlier Narda designs. Only the Nardalert XT has a vibrator alarm. The LEDs are extremely bright and color coded. The LEDs can be seen while wearing the monitor.
bullet
Ergonomics & Climbing: The Nardalert XT has two different types of mounting clips that are standard and two types of optional soft cases. One of these soft cases is designed to attach to a safety harness. There have been countless numbers of monitors that have been dropped while climbing towers and this is by far the best solution available to securely attach a monitor while climbing. |

SilverBuddy
Antimicrobial Silver Wipe
Germs are everywhere! When you have daily contact with people
and don't have time to wash your hands frequently, you can still protect
yourself from germs.
Teachers in contact with many children and people who handle
currency as part of their daily job functions should wash their hands often.
Shopping carts, runny noses, petting zoos, and public rest rooms are some of the
many other common encounters with germ covered surfaces.
Use wet or dry. SilverBuddy towels kill disease causing germs.
Use between hand washings to take advantage of the anti-bacterial properties of
Silver to reduce bacteria counts. Convenient 12x12 inch wipe can be used over
and over. Simply wipe your hands thoroughly! Easy to carry in pocket or purse.
Easy to pack in a lunchbox, briefcase, glovebox, or picnic basket.
SilverBuddy can be machine washed many times (cold, delicate
cycle and line dried) with no reduction in effectiveness. Also useful as a
microwave shield or minor wound/sunburn dressing. Very unique! |
