Features: Enter the alarm setting options to set the cumulative alarm value and the alarm value for the dose rate. When the radiation value exceeds the set value, the nuclear radiometer will automatically alarm. Daily use of nuclear radiation detectors helps avoid radiation hazards in everyday life. Nuclear 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 in real time. Nuclear radiation detectors are small and portable. Permanently store data in the event of a power outage. Beginners, seniors and advanced users can easily operate. The large LCD screen of the nuclear radiation detector allows you to easily and quickly read real-time values. Widely used in single safety protection monitors and radioactive indications, suitable for workers in the following fields: nuclear power plants, accelerators, iron and steel industries, chemical industries, isotope applications, industrial X and gamma non-destructive defect detection, Cobalt source processing, gamma radiation laboratories and environmental monitoring around nuclei. Equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the clear LCD digital display after processing by control micro-chip.
