JB4020 personal warning device for X-γ radiation


JB4020 personal warning device for X-γ radiation is a kind of intelligent instrument, mainly used for monitoring X, γ and β-ray radiations in various kind of radioactive workplace and protecting the safety of staff. This instrument is also able to measure dose rate and accumulated dose at the same time. It adopts the new powerful singlechip technology, its detector is a compensated GM counter, so this instrument has a wide measurement range and very good energy response characteristics, with the functions of overload indication and protection.
The Company has participated in drafting National Metrological Verification regulations JJG 1009 - 2006 "Direct Reading Personal dose equivalent (rate) monitor for X, γ radiation" of the People's Republic of China.


    High sensitivity, environment background can also be measured
    Simultaneous display of accumulated dose and dose rate
    Singlechip technology, multi-functions and small volume
    Easy and convenient operation
    Alarm threshold can be preset
  •     low voltage alarm
    Dose rate and accumulated dose alarm
    Accumulated dose can be stored for a long period of time in case of power failure
    With real-time clock function, clock running normally after shutdown
    Alarm modes: sound, vibration, sound+vibration
