Feature: 1. LCD Display: Large and clear, easy to read values, including data hold and maximum measurement, one key to lock data, manual/auto shutdown, safety value setting and large LCD display value with sound and light system. Everything is designed for your convenience. 2. Flashlight function: clearly see the value in the dark, the radiation warning light is divided into three kinds of display, green, yellow and red are divided into 3 colors, showing that red is the worst. There is a lot of radiation in the life scene, although it cannot be avoided one by one, but please stay away from the radiation as much as possible. 3. An electromagnetic field measuring instrument, three measurements: measurement of magnetic field radiation, electric field radiation and temperature. 4. Larger frequency range: The measurement frequency range is larger, up to 5HZ-3500mhz, the home EMF detector can be used to test TV, induction cooker, refrigerator, mobile phone, computer, wire, WIFI signal, wire tower and any other low-frequency home appliances, etc. 5. Multi-unit conversion: mG/T/(V/M)//, sound and light alarm, when the detection result exceeds the safe value, the instrument will automatically alarm. 6. Wide range of applications: measure the radiation of televisions, induction cookers, rice cookers, refrigerators, computers, electrical appliances, wires, etc. Specification: Material: ABS Power supply: 1*6F22 9V battery Automatic shutdown: 15 minutes of no operation Working environment: 0-40/32-104, 45%-80%RH Frequency range: 5Hz-3500MHz Magnetic field strength measurement range: 0.1-199.9mG / 0.01-19.99T Resolution: 0.1mG / 0.01T Alarm threshold:> 4.0mG /> 0.4T Electric field intensity measurement range: 1-1999V/M Resolution: 1V/M Alarm threshold:> 40V/M Ambient temperature measurement range: 050/ 32122 Resolution: 1/ Accuracy: 1.5/3 Package Included: FY876 host*1 9V battery*1 Manual*1 Instrument package x1
