Feature:1. TWO USES: One instrument for two purposes. The electric field and magnetic field are measured simultaneously. T for testing magnetic field radiation, V/m for testing electric field. This EMF meter can not test the RF value.2. PRECISE MEASUREMENT: Built-in high-precision electromagnetic radiation sensor, -control chip processor, can quickly and accurately measure electromagnetic radiation value.3. AUTO ALARM: Sound-light alarm, When the electric field value exceeds 45V/m, and the magnetic field exceeds 0.4T, the instrument will alarm automatically.4. MULTIFUNCTION: Testing average or peak value(Maximum) reading, and Data locking, one-key lock of the radiation value. The high-definition large-screen display reads more intuitively and clearly, at a glance.5. WIDELY APPLICATIONS: Widely used in homes, offices, living areas, industrial equipment, Power distribution room, high-speed rail, signal base station, etc.Specification:NF-601 is mainly used for electromagnetic radiation detection of electrical appliances, high-voltage lines, base stations, etc., to help people stay away from radiation sources and avoid radiation hazards!Features:TWO USES: One instrument for two purposes.
