Precision and Versatility at Your Fingertips: Equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the clear LCD digital display after processing by control micro-chip. Testing magnetic field radiation with optional units mG/µT, the electric field with unit V/m. Ultra-long battery life: EMF detector comes with a 700mAh Type-c lithium battery for long-lasting battery life. EMF reader automatically es off after 15 minutes of inactivity. The EMF meter features a large backlit LCD display that clearly displays real-time data and functions, ensuring you stay informed. The backlight ensures a clear display even in the darkest conditions. Visual and Audible Alarm: NOYAFA Radiation Detector features a three-color backlight display and audible alarms (can be turned off). Numerical readings and trend graphs provide you with a clear understanding of the current field strength data. Additionally, the intensity and frequency of audible alarms changes according to the measured value. User Friendly: EMF Detector is designed with your convenience in mind. Equipped with features like MAX measurement, Peak measurement, and Data Hold, this device allows for a comprehensive understanding of field strength values. The LCD screen makes readings easy, and it comes with an Automatic Shutdown and Low battery indicator to help conserve energy. Versatile Applications: RF mode can detect WiFi signals, 5G signals (below 3.5GHz), and microwave radiation from appliances like microwave ovens. ELEC and MAG modes can measure electromagnetic radiation emitted by household appliances such as televisions, induction cookers, rice cookers, refrigerators, computers, and power lines. It helps you with room layout and avoids placing you in high-radiation environments. Colour:White Material:ABS Package Contents: 1 x EMF Meter 1 x USB Cable 1 x English instruction manual <br /
