1、High Sensitivity: The nuclear radiation detector adopts professional Geiger counter and advanced geiger tube as the core sensor, which can accurately detect β, γ and X rays and update once per second. The detection range of the radiation detector is 20kev~3.0mev≤±30%(137Cs‑), and the testing accuracy can be up to 0.01uSV/h. 2、HD Display: High Definition 3.2inch LCD display, clear writing with backlight display, easy to use in dark environment. 3、Sound and Light Alarm: Whether the personal radiation detector screen is in sleep state or working state, when the detected radiation dose exceeds the alarm threshold, the Geiger counter dosimeter will emit a loud sound and flashing screen alarm to take care of your and your family's health in all aspects. 4、Wide Application: The radiation detector is widely used in the environment of existing ionizing radiation environment, such as home renovation, radiation production enterprises, health, nuclear laboratories, nuclear power plants, building materials, petrochemical industry, geological census, etc. It is the ideal choice for families, hospitals and workplaces. 5、Low Power Consumption: Built in powerful rechargeable lithium battery, the nuclear radiation detector only needs to be charged for 2‑3 hours, and the monitor can measure continuously for 24 hours after it automatically sleeps while working. Small and convenient, you can carry it anywhere you want to detect. This radiation detector can provide you with 24 hours full detection.
