Advanced GQ EMF-390 Multi-Field, Multi-Function
EMF Meter and RF Spectrum Power Analyzer

EMF-390 multi-function digital EMF meter is designed to be a portable device. It can be used as 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 connect 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 let user to read the data from upside down view easily.

EMF-390 has on board flash memory for data logging and saving. The data can be logged every second and can be downloaded into .csv format file with free software EMF-PRO.

GQ RF Browser is specifically designed for Cellphone, Cell Tower, Smart Meter, WiFi RF radiation monitoring.

Safety suggestion indicator provides a simple and easy way to understand overall radiation risk.

The device is equipped with an USB port, utilized for communication and external power supply/charging of the internal rechargeable Li-Ion 3.6V/3.7V battery.The GQ EMF-390 internal rechargeable battery can be charged with a standard USB port, USB charger or with a computer USB port. Using the external power, continuous data monitoring is possible. Using either power adapter you will not have to worry about the batteries charge condition or any data loss.The EMF-390 also has a real time clock on board for time related data measurement.

The meter installed multiple sensors to ensure maximum scale/range measurement and highest accuracy.

High sensitivity meter let you check EMF/RF radiation easily. Examples: computer mouse, car remote key, cell phone,cell tower,cordless phone, static electricity, electric field, WiFi, computer laptop, microwave, electric heater, hair dryer, vehicle engine, light, outdoor power line. With RF spectrum power analyzer, you can monitor the WiFi signal power, Smart meter signal power, spy wireless video camera signal, even track radio/TV signal in air.
