Wide bandwidth coverage and dualmode operation: supports and low frequency dualmode, accurately captures signals from base stations, microwave ovens, etc., meeting the needs of multiple scenarios. Efficient and convenient to use: easy to operate, able to quickly measure the electromagnetic radiation intensity around household appliances, wires, and industrial equipment. Strong lowfrequency detection capability: using advanced sensing technology, the lowest detectable low frequency electromagnetic field is 5 Hz. Electromagnetic radiation testing: measurement of radiation sources such as living rooms, offices, computer rooms, control rooms, cables, voltage lines, monitors, etc. Use scenarios Home environment: screen electromagnetic field exposure around living rooms, kitchen appliances, wireless devices, and power wiring. Office or computer room: assess EMF around computers, monitors, servers, and network cables. Industrial or controlroom setting: monitor electromagnetic emissions from cables, voltage lines, and other equipment in control rooms.
