DescriptionWith a large LCD display, the values are clearly displayed on the screen, which is easy for you to read and gives you a better experience. This detector detects both electric and magnetic field radiation for you, allowing you to get two important values in one test. Sound and light dual alarm function, when the detection value exceeds the safety value, it will automatically alarm.Data hold function: short press the "power/hold" key, the reading will be locked and the [hold] icon will be displayed on the screen, press again to resume normal measurement and the [hold] icon will not be displayed. Small size, easy to carry, can be used with one hand, can be carried around and used wherever you want.Radiation assessment function, can indicate whether the current radiation value is at a safe level, three color lights indicate the current magnetic field status: safe, alarm, avoid, if the electric field data exceeds the safe status, the screen will turn red to remind you.Wide range of applications. The tester can be used for electromagnetic radiation monitoring in houses and apartments, offices, outdoor and industrial places, electromagnetic radiation testing of cell phones, computers, TV sets, refrigerators and high-voltage cables, anti-radiation product testing, etc. Clothing, radiation protection film and other anti-radiation effect.Specification.
