Features: Enter the alarm setting-options to set the cumulative alarm value and the alarm value-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 for 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-chips.
