Advanced GQ EMF-390 Multi-Field, Multi-Function EMF Meter and RF Spectrum Power Analyzer,
and Now Including Datalogger
Latest version GQ EMF-390 is ready, this multi-function digital EMF meter is designed by GQ Electronics.
The GQ EMF-390 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, Schools and electronic repair shops.
The device's integrated Testing Features include Three-Axis Electromagnetic Fields: Electric Field, Radio Frequency and a 2.5Ghz RF Spectrum Power Analyzer. This EMF Meter is able to identify the common source of the EMF Detected/Measured, such as a Overhead Power Lines, In-Home Smart Energy Meter, 2.4GHz & 5GHz WiFi Signals, Food/Cooking Microwave, Cell Phone Tower etc.. It also has built-in audible and visual alarm to help users that may have Visual/Hearing impairments, and Now Comes with a Datalogger
EMF-390 has built-in flash memory and it is able to log real-time data EMF, EF and RF power every single second. Users are able download the data later using the free software EMF-PRO from GQ Electronics download page.

The GQ EMF-390 Meter can be used for EMF, ELF, EF, RF detection and monitoring both indoor and outdoor, as well as other similar environments. It can continually monitor radiation.
When connecting the device to a PC, the PC software can download the radiation data to the computer and the user is able to analyze the data at a later date. The GQ EMF-390 also has a high contrast black/white LCD module and a front flashing LED indicator.

The built-in electronic gyroscope
let users see the data from Portrait or Landscape Viewing angles.
GQ RF Browser is specifically designed for Cellphone, Cell Tower, In-Home 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 a 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 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 is installed with multiple sensors to ensure maximum scale/range measurement and highest accuracy.

High sensitivity EMF meter allows you to 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, indoor/outdoor lights, 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 over air signal.
