PERSONAL EMF ALARM
Attention all pacemaker wearers!
Attention all paranormal researchers!
Attention electrical sensitives!
What could be better than a meter which alerts you with a loud audible alarm when it encounters a field? How about a meter which allows you to set the sensitivity of the alarm? How about a 3 axis meter? How about a meter which does all this for AC magnetic fields, AC electric fields, and RF radiation?! This meter does all that, for under $200!!
We are very excited to offer this simple and useful item for anyone who wants to monitor their EMF environment without having to stare at their meter for hour after hour. Carry it with you to alert you when you become exposed to more radiation that you want. Set it in a strategic location to alert you when a field trips the alarm. You set the level (threshold) above which the alarm will sound. Can also be used as a nice analog meter to read field strength. Same specifications as our Trifield Meter.

TRIFIELD™ METER
EX100 Version
The TriField Meter is the only one which combines magnetic, electric, and radio/microwave detection in one
package. This meter combines all these unique features with affordable pricing for fast, reliable measurements of
electromagnetic pollution:
Continuous sampling analog readout;
Omni-directional electric & magnetic sensitivity;
Two separate scales for magnetic field readings;
Hand-held portability and simplicity.
The TriField Meter will accurately measure EMF pollution from these "hot spots" in your home, office, or work
environment so you can take steps for "prudent avoidance":
- poorly grounded wiring
- microwave oven doors
- dimmer switches
- cellular phones
- FM transmitters
- automobiles
- TV's & computers
- other electronic equipment

It is important to note that the magnetic and electric field settings of this meter are frequency weighted from 30 to 500 Hz, and calibrated at 60 Hz (a 50 Hz calibrated unit is available as a special order). What this means is that a 2 mG magnetic field at 60 Hz will read "2" on the meter, but 2 mG at 120 Hz will read "4". From 500 Hz to 1000 Hz, the response is flat ±20%. Above 1000Hz, sensitivity decreases with increasing frequency.
Have peace of mind and confidence in knowing where this body penetrating pollution is coming from, and how powerful it is, so you can protect yourself and loved ones. Instruction booklet and 9V battery included. One year limited warranty. Made in U.S.A.

Trifield Flat Frequency 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.
Trifield Flat Frequency Response Meter (Cat. #US150-F).....$149.95
Trifield "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/cm²)

3-AXIS GAUSSMETER WITH HARMONICS
In paranormal research, the presence of man-made 50 or 60 Hz EMF signals can give rise to "false" readings. Wouldn't it be great if you could set your EMF meter to ignore these ever-present signals and just pick up everything else? Now you can! With this meter you can look at just the 50/60 Hz signal, or just the harmonics, or just everything else. And you can compare that reading to the overall reading on the same screen at the same time! Adjustable back light too, because it was designed with paranormal research in mind.
Also perfect as an all purpose meter with high sensitivity. Great for distinguishing a 50 or 60 Hz signal from the higher frequency harmonic signals which often accompany power line magnetic fields.
- Bandwidth 30-300 Hz

- Switch between milliGauss or microTesla via menu
- Low battery indicator
Alkaline battery (included) typically lasts ~20 hours at default backlight setting. Feature rich and easy to use. Great price too! 1 year wty. Made in USA.

Finally, a way to actually "see" DC magnetic fields from permanent magnets or magnetized metals without messy iron filings! You can use this amazing film over and over to view the location and number of poles on any magnet. Just lay the card on the magnet to see the polar pattern. Magnetic poles appear as dark areas and the light areas represent where the N and S poles meet. A great inexpensive magnetic detector for finding objects in your environment that have become magnetized. Uses no batteries. Also great for science projects. Dimensions: 2-1/2" x 4"
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. Two models in stock: -20 to +20 and -100 to +100 Gauss.
For Strong Field Applications
A coiled cable transverse probe (High Linearity Hall Generator) is included providing nearly linear response from DC to 10 Hz. Useful 4 ranges covering 0 - 20, 200, 2000, 20,000 Gauss with a 3% accuracy guarantee. Two year parts and labor warrantee. 200mV DC recorder output (which can be used with
