Feature: 1. GM Counter with Energy Compensation: Geiger counter nuclear radiation detector can detect X ray γ ray and β X ray. The sensor is added with energy compensation, X ray detection is more accurate. 2. Built in Memory: The nuclear radiation detector has a built in memory, and some data such as cumulative dose value, dose rate alarm threshold and dose alarm threshold will not be lost after power failure. 3. Multiple Screen Display Functions: You can arbitrarily adjust the alarm threshold, switch between Chinese and English, screen backlight, real time dose rate curve display function, etc. 4. Multiple Functions: Enter the setting interface to adjust the alarm preset value, time, Chinese English switching backlight mode, curve display, particle sound switch and other functions. 5. Good Features: The nuclear radiation detector has a membrane keyboard, is beautiful in appearance, small in size, light in weight and strong in sealing. It is dustproof, oil stain proof, acid and alkali resistant, earthquake resistant and has a long service life. 6. Fixation of Battery Cover Screws: The battery cover screws are fixed to prevent the inconvenience caused by the battery falling due to accidents caused by special reasons in special scenes. 7. Hanger Back Clip: When your hands are occupied during work, you can hang nuclear radiation detector on your clothes or belt.
