Description Features: This meter can test electric field radiation and magnetic field emission to reach the optimaltest result. It is used to test and learn electromagnetic radiation situation indoor and outdoor. Electromagnetic radiation monitors respond quickly to radiation and provide timely alarms in high-risk environments. The instrument is highly flexible and can measure environmental backgrounds. The detection value is-updated inrealtimes. Electromagnetic radiation detectors are small and portable. Permanently storesdata in the event of a power outage. Beginners, seniors and advanced users can easily operate. The large LCDscreen of the electromagnetic radiation detector allows you to easily and quickly readrealtimes values. Widely used in single safety for protections monitors and radioactives indications, suitable for workers in the following fields: electromagnetic powerplants, accelerators, iron and steelindustries, chemicalindustries, isotopes applications, industrial and-gammas non-destructive defect detection, Cobaltssource processing, gammas radiation laboratories and environmental monitoring around nuclei. Equipped with a built-in electromagnetic radiation sensor, which can display the radiation values on the clear LCDdigital display after processing by control micro-chips.
