Multi Function 4 In 1: Electromagnetic radiation detectors can simultaneously test electric field and magnetic field radiation. The meter can also detect ambient temperature (C/F) and with flashlight function. Sound light alarm: With warning light display function, when the test result exceeds the safety value, the instrument will automatically trip. LCD digital display: Built-in electromagnetic radiation sensor, data storage and clear LCD backlight display, one key can lock the radiation value and read the value easily. Portable design: The compact size is easy to use and operate, easy to move or for on-site measurements. Measure Radiation: Electromagnetic radiation can test households and apartments, offices, outdoor and industrial sites. also perfect for mobile phone, computer, TV, refrigerator and high voltage cable radiation test.
