FS2011and FS2011and radiation individual alarm device is collocated with highly flexible Geiger counting tube as detector it is mainly responsible for monitoring the radiation of X, and hard rays in various radioactive work areas. It is featured as swift response and broad measurement scope. Wide applications, it is widely applied in the individual safety protections monitor and radioactive indication for work personnel in the following fields: nuclear power plant, accelerator, iron and steel industry, chemical industry, isotope application, industrial X and y non-destructive flaw detection, Y radiation, radioactive laboratory and surrounding environment monitor of nuclear facilities. Features: This instrument is mainly used for radiation monitoring of X, and rays. With detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation. Configured LCD colorful screen, 128x64 clear display definition, you can see the real time data clearly. Equipped with Chinese and English operational interface, you can set parameters, easy and convenient to use. Real-time measurement and display of dosage equivalent rate and accumulative dosage in the work area. Permanent data storage upon power cutoff. Low power consumption and battery under-voltage indication function. The instrument can preset the alarm value of dosage rate and accumulative dosage. Three selective alarm modes design: sound, light and vibration. There are 5 measurement units switchable: dosage rate in the unit of u Sv or h, u Gy or h and m R or h, CPS, CPM. The calendar, time and accumulative data can be stored permanently during the battery replacement. Wide applications, it is widely applied in the individual safety protections monitor and radioactive indication for work personnel in the following fields: nuclear power plant, accelerator, iron and steel industry, chemical industry, isotope application, industrial X and y non-destructive flaw detection, Y radiation, radioactive laboratory and surrounding environment monitor of nuclear facilities.
