Radio frequency (RF) radiation and electromagnetic fields surround us at all times in varying intensity. Strong fields can be found around cell phone towers and high voltage facilities. These fields can be detrimental to electronic devices as strong electromagnetic fields can actually change electrical currents, causing some electronics to malfunction.

Another increasing issue is the concern about the negative health effects from high intensity radio frequencies or electromagnetic fields. While there is little strong evidence of this many people would rather not take the chance. Whatever the reasoning this meter is designed to measure high frequency radiation in a range from 50MHz all the way up to 3.5GHz.

It has the ability to trigger an alarm if radiation levels exceed your preset number. Using this meter is a great way to test exactly the energy being produced and to quantify changes to electronics or adjustments to frequencies.
