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, Vm 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 45Vm, 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: 1~1999Vm Accuracy: 1Vm Alarm Threshold: 45Vm 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: less than 0.5s Date Lock: √ o-visual Alarm: √ Radiation Assessment: √ Backlight: √ Power Supply: 2 * AA Dry Battery(not included) Operating Temperature: 0~50 celsius 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)
