Product Description
The GQ EMF-390 Advanced Multi-Function Digital EMF ELF Meter is a portable and convenient device created by GQ Electronics in Seattle, USA. It is suitable for general-purpose testing, detection, and various scientific applications, including assessing power lines, Wi-Fi, cell phones, cell towers, microwaves, smart meters, and more. This device integrates features such as a three-axis electromagnetic field, electric field, radio frequency, and radio spectrum power analyzer.
The meter excels in identifying and recognizing common sources of EMF/RF measurements, such as power lines, Wi-Fi, cell phones, cell towers, microwaves, etc. It includes a built-in audible and visual alarm for added convenience. The EMF-390 can be used for detecting and monitoring EMF, ELF, EF, and RF both indoors and outdoors, as well as in similar environments. When connected to a USB port for power, it continuously monitors radiation. Additionally, when connected to a PC, the included software allows users to download radiation data for later analysis.
Equipped with a high-contrast black/white LCD module and a front LED indicator, the device offers user-friendly features. The unique GQ RF browser feature visually represents RF radiation on the screen, providing an accurate display of estimated digital RF transmission data in bytes and RF power spectral histograms. The EMF-390 also boasts built-in flash memory, enabling real-time logging of EMF, EF, and RF power data every second. Users can easily download this data later using the free EMF-PRO software.
