Specifically designed to cover the new 5G bands, this is an EMF measuring device to alert workers near antennas. It continuously scans for electromagnetic waves and, via its built-in alarm and visual system, alerts users whenever the acceptable limits have been exceeded.

• Unit measures frequencies from 1 MHz - 40 GHz
• Unit features an LED visual alarm, an audible alarm and a low battery indicator
• Unit comes with a case, wrist strap, arm band, lanyard, connecting adaptor and two N batteries

Quickly identify and pinpoint the smallest gas leaks. 16" flexible gooseneck allow for easy access into hard-to-reach locations. The thumb-controlled sensitivity adjustment eliminates background gas levels. Visible and audible alarm activates at 10% (LEL) Lower Explosive Limit for methane. Unit comes with three C batteries .

Designed for use near antennas, this monitor continuously records the electromagnetic field level and alerts the user to potential over-exposure. It is lighter than the previous model, making it easier for workers to wear on the job. The longer battery life and extended memory capacity enable more measurements to be recorded.

• Unit measures frequencies from 1 MHz - 40 GHz
• Unit features an LED visual alarm, an audible alarm, a vibration alarm and a low battery indicator
• Unit comes with a case, arm band, USB cable, USB power adaptor and EME guard analysis software
