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
- strong analog RF 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. # A150-F).....$129.95
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/cm˛)

SPECTRAN® Low Frequency

Electric & Magnetic Field Spectrum Analysis
Here's a neat combination meter which affordably gives both frequency and field strength information for low frequency electric and magnetic fields. Hand held and completely self contained, with a huge LCD display. Includes rechargeable battery and input for external DC power supply. Great price too!
- Superfast FFT spectrum analysis
- 3 axis magnetic field measurement
- Frequency and signal strength display!
- Offers readout in G, T, and A/m
- High-resolution multi-function display
- Exposure limit calculation!
- Typical accuracy: 5%
- Audio output with volume control
Comparing readout against established exposure limits:
Exposure limit calculation can be a complex and awkward procedure even for the professional, as most of the time a chaotic mixture of different frequencies, modulations and signal strengths is present.

Not so with SPECTRAN® units: They can calculate several authoritative exposure limits, precautionary limits and recommendations at lightning speed (simply select which limit you want via a button) and display the measured levels as a % of the selected limit and a practical bargraph display.

PACE-ALERT™
Peace of Mind for Pacemaker Wearers
Pacemakers and implantable defibrillators are vulnerable to strong electromagnetic fields. Manufacturers of these devices have set EMF exposure limits, but how is the user to know if his work or home environment is safe?
PaceAlert is the first and only meter/alarm designed specifically with pacemaker safety in mind. Simply turn the unit on and it will warn with LED lights and audible alarm if it encounters EMF near the limits for proper and safe operation of implanted devices. PaceAlert monitors AC magnetic fields, AC electric fields, and radiofrequencies simultaneously. Common sources of strong fields include microwave ovens, power tools, hair dryers, vacuum cleaners, electric ranges and toaster ovens, electric circuit boxes, welding equipment, etc.
Alarm thresholds:
- 4 kV/m for electric field at 50/60 Hz
- 1.5 Gauss magnetic field at 50/60 Hz
- 100 V/m RF from 500 kHz – 6 GHz
No adjustments needed, no complicated interpretations to make. If you hear the alarm, you are too close! LEDs will indicate type of EMF (electric, magnetic, or RF). Convenient size fits in pocket or purse. Or it can be worn as a necklace or on belt clip. Gets about 20 hours on standard 9V alkaline battery, 9 hours with rechargeable. Low battery indicator. One year warranty. Annual re-calibration available.

In The News:
A research team at the Academic Medical Center at the University of Amsterdam examined the effects of GPRS and UMTS signals on critical care equipment such as ventilators and pacemakers. There were almost fifty incidents of EMI impacting the devices, and 75 percent of these could be characterized as significant or hazardous. Problems observed - a total switch off and restart of mechanical ventilators, complete cessation with no alarm sounded of syringe pumps, and incorrect pulsing of an internal pacemaker. Second-generation phones based on GPRS technology generated the most serious instances of EMI—sometimes from as far away as three meters.

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.
