Recommended application: environmental monitoring (nuclear safety), radiological health monitoring (disease control, nuclear medicine), homeland security monitoring (customs), public security monitoring (public security), nuclear power plant, laboratory and nuclear technology application, but also applicable to the renewable resources industry waste metal radioactive detection and family decoration building materials testing.

①　Pie detector

②　High-strength ABS shell

③　Large screen display, all data with the same screen display, with backlight function

④　16G SD card (store 400,000 data)

⑤　 A machine, can detect surface pollution, ray, can also detect X, ray

⑥　A variety of external probes can be extended externally.

⑦　Overthreshold alarm, detector fault alarm, low voltage alarm, over-range alarm

(1) High integration: the instrument integrates sodium iodide (low potassium), which can measure the environmental dose rate in real time and quickly identify radionuclides;

(2) Nuclide database is large: Nuclide database is divided into five categories: natural, medical, industrial, SNM and nuclear industry;

(3) Using digital T-type filter forming technology: both energy resolution and pulse passing rate;

(4) Adopt a variety of power supply modes: built-in rechargeable lithium battery, external charging power supply;
