Geiger counter tube adopts domestic and foreign micro GM counter, jointly developed by Wanyi Technology and Russian Counter Company. With stable and reliable data, Geiger Counter Tube can quickly detect hard β, γ and X rays in the environment or products in real time, and quickly find radioactive sources. It can be used for the development of personal dosimeter and radiation detector. The probe sensor of radiation monitoring systems has been calibrated from the factory, and the user can directly read the data through the RS485 digital communication protocol.
