Application and characteristic:
DM37 portable radiacmeter is used in dose protection for measuring neutron fluence rate and γdose rate of nuclear reactor, nuclear power station and other places of isotopes application.It is easy to use,no need to change probe when you measure n、γrays.Low low power consumption circuit(≤400mW). Rechargeable batteries provide power can continuously work for above 24h.Digital dissimplified circuit design,easy to operate,stable performance and easy to carry
