The radio frequency meter comes with a spherical triaxle sensor for detecting electro-magnetic radiation. The radio frequency meter can be used for measuring transformers, as well as for evaluating magnetic fields produced by computer screens, televisions, industrial installations including electromotor and soldering behind protective screens. It radio frequency meter is also capable of detecting radiation emitted by wireless systems such as wireless LAN, GSM or for determining the radiation of microwave ovens. With a frequency range of up to 3.5GHz, it can be used for high frequencies. Thanks to its triaxle sensor, it can avoid the need for doing conversions for each axis. The small electronic smog meter is useful in the industrial field as well as in laboratories. Easy to use, quick and accurate.
