Application and characteristic:

dosimeter an pocket intelligent multifunctional instrument adopting new type single chip is mainly used for monitoring X ray and γray. 1.8”LCD color screen full screening personal dose rate, the cumulative dose, real-time clock, measuring time and alarm threshold andautomatic sound-light alarm.The power supply is environmental lithium battery continuously providing power. The main technical parameter meets the national standard and international standard,is widely used in these areas of radiation station, custom, industrial nondestructive inspection, accelerator,nuclear power station, nuclear submarine, radioactive medical treatment,isotope application,medical cobalt treat and monitoring environment around nuclear facilities.

● high sensitivity,response to environment backgroundly

● continuously adjustable alert threshold

●All measurement information is displayed one time on the colour screen

●Low power dissipation,small volume,easy to carry

● Intelligently check choke

● with USB interface,can be used as USB flash disk

● Additional MP3 / 4 playing and photo browsing
