AT2343智能γ輻射檢測裝置  的詳細介紹
INTELLIGENT GAMMA RADIATION DETECTION UNIT AT2343
 

 Provides radiation monitoring of territories and industrial units as a part of automated system




Features

- Detection of upper limit exceeding of absorbed dose rate measuring range
- Measuring results keeping in the memory
- Serviceability self-testing and its result output on the display
- Real time watch
- Data transfer and control command receiving by interface RS 485
- Serviceable after short-term (not longer than 5 min) gamma radiation influence of dose rate of 20 Gy/h
- Dust- and water proof design
- Industrial radio-interference level meets GOST 23511-79 requirements

Application

- Environmental radiation monitoring
- Enterprises of radioactive waste treatment, storage and burial
- Nuclear power plants
- Radiation sensitive enterprises and companies

Six GM tubes of big volume provide high accuracy of low gamma radiation dose rate measuring for a short period of time. Built-in microprocessor system provides data transfer of measurement results and detection unit state on a request from an external device by RS 485. It is possible to switch GM tubes over to small volume and measure high radiation level.
