Walmeck Handheld Radiation Detector Geiger Counter Meter, Electromagnetic Radiation Tester Dosimeter

TWO USES: One instrument for two purposes. 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 RF value. PRECISE MEASUREMENT: Built-in high-precision electromagnetic radiation sensor, -control chip processor, can quickly and accurately measure electromagnetic radiation value. AUTO ALARM: Sound-light alarm, When electric field value exceeds 40V/m, and magnetic field exceeds 0.4µT, instrument will alarm automatically. Power Supply: Built-in 700mah high-performance battery. USB direct charging, convenient and durable. high-definition large-screen display reads more intuitively and clearly, at a glance. WIDELY APPLICATIONS: Mainly used for testing routers, bt, radio equipment, TVs, computers, printers, microwave ovens refrigerators, cell phone towers, for low frequency household appliances.
