TRIFIELD METER (MODEL TF2)
Brings The Trifield Meter Into The Digital Age!
The original Trifield meter has been around forever and it was a favorite of ours. This improved version is even better! The TriField Meter will test EMF pollution from "hot spots" in your home, office, or work environment so you can take steps for "prudent avoidance". Completely self-contained, no parts to lose. You still get 3 meters in one. Three axis for magnetic and extremely wide frequency response.
Here are some of the upgrades:
- A very nice digital display allows for more precise measurements
- Frequency flat and weighted measurements can be done by the same meter
- The RF portion is 1000x more sensitive and can read frequencies up to 6GHz
- Includes backlight and sound function
- Shows both instantaneous and Peak readings
Gain 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 sheet and 9V battery included. 1 year ltd warranty. Made in USA.

Handy Meter (Cat. #A145) ............. $159.95
Versatile and Great Value
When your main concern is price, this meter fits the bill. Large backlit display is easy on the eyes and displays both electric field and magnetic field readings simultaneously. Makes quick work of checking for emissions from powerlines, household wiring, appliances, and anywhere that electricity is flowing.

POCKET PF5 METER
Super Simple and High Accuracy
The PF5 is our newest power-frequencies detector. The PF5 measures electric and magnetic EMFs from house wiring, including those from appliances at home or at work. covering frequencies from 20 Hz to well over 50 kHz. This enables the PF5 to measure the higher frequency electric and magnetic fields emitted by induction cooking hobs, solar-panel inverters, 'energy-saving' compact fluorescent (CFL) lamps and LED lights.
These are amongst the most concerning new sources of our electromagnetic field exposures as the currents they induce in your body are proportional to the frequency. So a magnetic field at 24000 Hz (24 kHz) will induce 400 times more current in your body compared with same strength of field at 60 Hz. Induction hobs, in particular, induce some of the highest internal electric currents in your body in the VLF frequency range. Such currents have been shown to significantly affect the nervous system.
The PF5 is an easy to use, pocket sized, accurate, power-frequencies meter which is ideal for carrying around. It measures both electric and magnetic fields. One button operation. Clear level indication with colored LED lights. So simple!
- A line of coloured LEDS shows the level
- Electric fields range: 5 - 200 V/m
- Magnetic fields range: 0.2 - 20 mG
- Resolution: 8 LEDs plus 7 middle points
- Accuracy: 50 to 2000 Hz ±10%
- Accuracy: 20 to 50000 Hz ±3 dB; with a useable extended response from 15 Hz - 70 kHz
- Battery: 9V Alkaline or Rechargeable
- Battery life: 25 hours (normal alkaline)
- Low battery (6.7V) shown by red V/m LED
|What is unique about this meter? magnetic and electric field in one meter, super easy to use, lighted, good accuracy|

ESI 24 EMF MONITOR
Detects & Displays All 3 EMF Types at Once
The very unique ESI 24 checks for all 3 types of EMF: magnetic fields, electric fields, and radiowaves/microwaves simultaneously. Easy to interpret RED / YELLOW / GREEN LED lights indicate EMF level and are supported by a loudspeaker that gives an audible indication of field strengths. Sound frequency/intensity changes with increasing field strengths. Sound can be turned off if you prefer. Allows for quick and easy localization of the sources of different types of EMF. The display shows 5 different levels, ranging from extremely low (i.e. no significant radiation exposure) to too strong for prolonged exposure and distinguishes how much for each radiation type. Super easy and super sensitive.

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.
