Triple Axis EMF Tester
Designed to provide a quick, reliable and easy way to measure electromagnetic field radiation levels around power lines, electrical appliances and industrial devices with readout in milliGauss (20,000milliGauss) or microTesla (2000 microTesla).
Provides three axis (X, Y, Z direction) electromagnetic field measurements. Calibrated to measure EMF radiation with a wide bandwidth of 30Hz to 300Hz.
Comes with sensor with 3-foot (930mm) cable, 9V battery, hard carrying case, and user manual.
8GHz RF EMF Strength Meter
A handy tool for monitoring frequency radiation in the 10MHz to 8GHz range, the Extech 480846 RF EMF Strength Meter is ideal for mobile phones, cell phones, base stations, locating RF hotspots, wireless network (Wi-Fi) detection, RF "Electrosmog" detection, and microwave oven leakage. It features non-directional measurement with three-channel (triaxial) measurement probe, maximum hold and average functions, and manual store/recall of up to 99 data sets. The 480846's measurement optimized for 900MHz, 1800MHz, 2. 7GHz, 3.5GHz, and 8GHz ranges. If an RF measurement exceeds a user selectable threshold, an audible alert will sound.

Measures EMF strength of low frequency (30Hz-300Hz in this case) portion of AC MAGNETIC FIELD (NOT AC electric field, too) from any one of 3 directions in milligauss (mG) or microteslas (uT).
This is NOT giving you a single value calculated from separate readings but rather 3 separate readings from each of 3 directions. It has a hold button to freeze a reading.
Because cell phones and microwaves are in a much higher frequency range, this product does not measure EMF (RF) at those frequencies. You would want a separate meter for that.
The 3-axis Thor's hammer like sensor may at first seem of questionable value, but it does add some convenience.
The Achilles Heal of this instrument, and the reason this is 2 stars and not 4 or 5, is that according to Extech Sales and Engineering, and confirmed with them as well, this model is HIGHLY INACCURATE for LOW EMF readings .. a fixed +/- 8.3 milligauss. This would mean a reading of 2 milligauss is actually 2 +/-8.3 milligauss. This is because the 4% accuracy is not of the displayed value but rather of the the value of the end of the measurement range (200 milligauss x 4%). Since so much of the consumer use of EMF checking is in the single and low teens mG, this is unfortunate.
To their credit Extech is up front about this unit being mostly for noting the existence of stronger EMF at low frequencies, not necessarily for quantifying it.
- Measures EMF at 30Hz-300Hz low frequency range, which covers most EMF generated by AC power in most homes/offices. 60Hz (U.S.) and much of the EMF generated by resulting harmonic frequencies ..Read more ›
