The RAD-S200 waterproof radiation probe uses an advanced Geiger (GM) sensor as the core sensing device, with stable data and responsive points, which can quickly detect hard �², �³ and X-rays in the environment or in liquids in real time (energy compensation type), and quickly find radioactive sources and measure the dose rate in the environment or in liquids in real time. Mainly used for radiation monitoring system integration, X-ray machine leakage, security inspection machine, hospital, medical wastewater, lakes, oceans and other occasions, factory has been calibrated, using RS485modbus-RTU protocol output, users can directly read the data through digital communication protocol.
