Ideal for use in any EMF measurement application including RF electromagnetic wave field strength measurements, mobile phone base station antenna radiation power density measurement, radiation safety level testing, locating RF host spots in the workplace or at home, microwave oven leakage tests, RF 'electrosmog' detection and detection wireless networks, the Extech 480836 is a must-have for any EMF measurement professional.
Capabable of measuring electromagnetic field radiation with frequency from 50MHz to 3.5GHz with optimised measurements for 900MHz, 1800MHz and 2.7GHz, the Extech 480836 is also capable of carrying out measurements in different units that can be selected from a dedicated button on the front of the tester (mV/m, V/m, μA/m, mA/m, μW/m, mW/m², W/m², μW/cm², mW/cm²).
To make obtaining a measurement significantly easier, the Extech 480836 comes with a non-directional (isotropic) measurement probe to ensure that EMF radiation can be detected from any direction.
This meter comes with a selection of additional accessories as well including MAX hold, Average calculation, manual storage and recall of up to 99 records and an audible alarm with user-programmable threshold.

Review by Dimitris (Posted on 23/02/2013)
I've used this meter to test emf from mobile phones/mast, DECT phone and WIFI. I am very pleased so far, its a well built product with lit display. Some of my measurements;
EMF from mobile phones: 5-15mW/m2
EMF from DECT phone: 80-100mW/m2
EMF from DECT base: 2.5-3W/m2!
EMF from WIFI internet: 30-50mW/m2
EMF from mobile must antenna: 4-5mW/m2
I would definitely recommend this product to anyone who wants to protect himself from harmful emf radiation.
Recommended emf for 24/7 use: 0.1mW/m2
