Designed to measure the electromagnetic field value of the Radio -Frequency. It can do a non-directional (isotropic) measurement with a three-channel measurement sensor. The non-directional electric field and high sensitivity also allow measurements of an electric field in TEM cell and absorber rooms. 

The meter can be used to indicate the electromagnetic pollution generated artificially and can be used for all types of radio broadcasting and TV transmitters produce electromagnetic fields.
