The electromagnetic radiation detector
GQ EMF-390 is a 3-in-1 multi-field electromagnetic radiation sensor for general purpose testing, detection and other scientific applications. With this meter, you can measure electromagnetic fields, electric fields, as well as radio frequencies around you.
Performance
With the GQ EMC-390, you can perform EMF, ELF and EF monitoring as well as detection indoors and outdoors, or in other environments. Indeed, this meter includes the detection function of electromagnetic fields, electric fields, radio frequencies up to 10 GHz. In addition, you can also analyze power spectra thanks to the additional function of this sensor. You will be able to see the RF radiation or high speed RF signal accurately on the screen and have the estimated RF transmission data as well as the RF power spectral histogram. With this device, you will also be able to identify the common source of the measured EMF and RF such as power line, cell phone, WiFi, cell tower, etc. Finally, thanks to its built-in flash memory, GQ CEM-390 is able to record data in real time with the added time stamp.
Mode of use and connectivity
The electromagnetic radiation detection device is really simple to use. All you have to do is read the user manual carefully and follow the instructions to the letter. All you have to do is turn on the device and it will automatically detect EMF, EF and RF radiation around you. To retrieve the historical data that the detector has recorded, you can connect it to your PC. In fact, you can connect it to your PC thanks to its USB cable that also serves as a charger and by downloading its software from its website. Indeed, it is equipped with a USB port and an internal rechargeable battery of Li-Ion 3.7 V.
Design
The GQ EMF-390 electromagnetic radiation sensor is designed with a simple and modern design. In fact, it is designed with a small all-in-one screen with a traditional analog style display. You can easily read and understand the data recorded by the sensor. Below the display of the radiation detection device, you will find the control panel of the device which consists of 4 buttons. Apart from that, this device is quite small so you can store it in your handbag, case, etc. You can carry it with you all the time and use it anywhere and anytime.

SO GLAD I PURCHASED THIS!
Solid, compact, easy to use (was already charged) with enclosed Quick Start Guide. Quickly determined that RF rather than EF or EMF was my concern here. Able to charge by plugging included USB cord into my phone charger. Everything fits into included case. Looking forward to mapping levels in different areas of home, yard & neighborhood. Very pleased!<br />
It's given me valuable information regarding my microwave.
The main reason I bought this was to see if it was safe to be close to my microwave when cooking. I found that despite the microwave being new and a good brand it would set of the alarm on this meter if I stood within a few feet of it. Funny, just moving a couple feet farther way and no problem. I'm happy I bought this.
The meter works great
The meter works great. It came fully charged and I haven't had to charge it since I bought it about two months ago. I used it primarily to measure EMF from transmission lines near a house I was thinking about buying. I did not buy it after it failed the EMF test. I used it at other houses I toured. It's also useful for locating Wi-Fi signals and dangerous ELF sources.
