Check electrosmog emissions from your electrical wiring and appliances

Just turn it on, set it to magnetic or electric field detection, and begin! This Digital Combination Meter hasd the same features and configuration of the ELF-3030B, but has an extended frequency range from 5 Hertz to 100 Kilohertz, which includes the higher frequencies created by, for instance, energy-saving lamps, electronic dimmers, and switching-mode power supplies.:

It has an audio sounder which sounds like a Geiger counter, increasing in intensity as the field strength increases

Easy to operate, easy-to-read display

Comes complete with manualand standard 9-Volt battery.

Check electrosmog emissions from your electrical wiring and appliances

Just turn it on, set it to magnetic or electric field detection, and begin! This Digital Combination Meter boasts several distinct advantages for a meter in this price range:

The operating manual is in 10 languages: English, French, German, Italian, Spanish, Dutch, Danish, Swedish, Japanese, and Chinese.

Featuring 10 LED lights, each denoting a calibrated level of radioactivity, covering a range from 0 to 7.5 microsieverts per hour. The LED's are further grouped into bands of green, yellow, and red. There is a choice of a 10-second or a 10-minute counting period and if, within any 1 second period, radioactivity over 15 microsieverts is encountered, GEM II will cease counting and display a special array of flashing/warning lights.
