GTH500( B) Carbon monoxide sensor GTH500&# 40; B) Working principle of carbon monoxide sensor

Description :

　　GTH500 (B) Carbon Monoxide Sensor Product Introduction: The GTH500 (B) carbon monoxide sensor is mainly used to monitor the concentration of carbon monoxide in the gas environment underground in coal mines. It can achieve on-site monitoring and remote sensing of various internal and external fires caused by coal spontaneous combustion, transportation tape, etc. in harsh environments such as gas and coal dust explosion hazards. Adopting high-performance imported electrochemical components, various anti-interference measures are taken in the hardware and software design of the whole machine to meet the electromagnetic compatibility requirements stipulated by relevant national standards. It has the characteristics of stable performance, high measurement accuracy, fast response speed, fault self checking, sturdy structure, easy use and maintenance.
