JB4020 X, gamma radiation personal alarm

brief introduction
The JB4020 X - γ Radiation Personal Alarm is an intelligent instrument mainly used to monitor the radiation of X, γ, and hard β rays in various radioactive workplaces, and to protect the safety of personnel engaged in and exposed to radiation. It adopts a new type of microcontroller technology with strong functions, and the detector adopts a compensated GM counter tube, so the instrument has a wide measurement range and good energy response characteristics.

Instrument features:
The instrument has high sensitivity and can also measure the environmental background

Simultaneous measurement of cumulative dose and dose rate

Adopting microcontroller technology, with multiple functions and small size

The instrument is easy to operate and convenient to use

Battery undervoltage and overdosing rate alarm

The instrument can preset the dose rate alarm threshold

Can be set as sound and light/vibration alarm mode

Main technical indicators:
