GQ Electronics EMF-390 EMF & RF Meter

GQ Electronics EMF-390 EMF & RF Meter

The EMF-390 multi-function digital EMF meter is designed to be a portable device. It can be used in industrial, commercial maintenance, research, evaluation, simulation and other analytical or scientific applications in areas such as industrial plants, public utilities, universities, laboratories and electronic repair shops.


The device integrated testing features include three axis Electromagnetic Fields, Electric Field, Radio Frequency and Radio Spectrum Power Analyzer. The meter is able to identify the common source from EMF measured, such as Power Line, WiFi etc. It also comes with built-in audible and visual alarm. It can be used for EMF, EF, RF and 5G network detection and monitoring both indoor and outdoor(protected), as well as in other similar environments. It can continually monitor the radiation. When connecting the device to a PC, PC software can download the radiation data to the computer and the user is able to analyze those data later. The device also installed a high contrast black/white LCD module and one front LED indicator.

The built-in electronic gyroscope lets the user read the data from the upside-down view easily.
