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. The electric field and magnetic field are measured simultaneously. µT for testing magnetic field radiation, V/m for testing electric field. This EMF meter can not test the RF value. PRECISE MEASUREMENT: Built-in high-precision electromagnetic radiation sensor, micro-control chip processor, can quickly and accurately measure electromagnetic radiation value. AUTO ALARM: Sound-light alarm, When the electric field value exceeds 45V/m, and the magnetic field exceeds 0.4µT, the instrument will alarm automatically. 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. WIDELY APPLICATIONS: Widely used in homes, offices, living areas, industrial equipment, Power distribution room, high-speed rail, signal base station, etc. Specifications: Electric Field Measurement Range: 1~1999V/m Accuracy: 1V/m Alarm Threshold: 45V/m Magnetic Field Measurement Range: 0.01~ 99.99µT Accuracy: 0.01µT Alarm Threshold: 0.4µT Test Bandwidth: 5Hz~3500MHz Test Mode: Dual-mode simulyaneous measurement Sampling Time: <0.5s Date Lock: √ Audio-visual Alarm: √ Radiation Assessment: √ Backlight: √ Power Supply: 2 * AA Dry Battery(not included) Operating Temperature: 0~50 Material: ABS Item Size: 124 * 59 * 29 mm / 4.88 * 2.32 * 1.14 inch Package Size: 12.5 * 6 * 3 cm / 4.92 * 2.36 * 1.18 inch Package Weight: 210g / 7.41oz Package List: 1 * Electromagnetic Radiation Detector 1 * User Manual (English)
