Product Profile:
AT1117M neutron radiation detector is a hand-held instrument. It is mainly used to measure the radiation dose rate and dose of neutron. Besides, there is a GM counter in the host, so it can also measure the radiation dose rate and dose of gamma.
Product Principle:
The neutron probe transmits the measurement data to the host computer for processing, and the final measurement results are displayed on the host screen. Users can store measurement data manually. Instrument arithmetic guarantees the continuity of measurement and can analyze the measurement results in real time.
Product applications:
Dose monitoring in nuclear power plants, manufacturing plants, scientific research laboratories, medical institutions, etc.
Product characteristics:
Rapid adaptation to changes in radiation levels
Wide energy range
Sound and light alarm signals
Self checking
The measurement results can be stored in the instrument.
It can be used in bad weather.
