ShanghaiHY-802 Radiation Monitoring Instrument (Neutron)

The HY-802 neutron probe serves as a basic unit for area radiation monitoring, used to measure neutron dose rates in the environment. By reflecting the neutron radiation levels in the environment in real time, it safeguards personal safety. It is widely used in nuclear power plants, reactors, accelerators, and other places that produce neutron radiation. The HY-802 neutron probe uses a moderator structure to ensure detection efficiency across various neutron energy ranges. It incorporates a low-noise preamplifier and a low-power linear power supply to ensure long-term operational stability. It provides RS-485 serial communication using the standard Modbus protocol, allowing direct connection to modern digital measurement systems or connection to a radiation monitoring host as a sub-unit.

Product Description

Features

●   This instrument uses a high-sensitivity  3  He proportional counter tube detector, which is fast and   easy to use;

●   The unique three-layer spherical design of the absorption layer/reflection layer/slowing-down layer detects neutrons   with energy up to 2 GeV, which can be used for proton beam detection and is suitable for accelerator fields   ;

●   The precise shielding structure around the detector effectively suppresses the influence of γ rays on neutron measurement,   and the γ suppression performance is good;

●   It can be used as a portable instrument or a fixed neutron dose monitoring instrument.
