GJG5H Infrared Methane Metal Detector in Security and Protection

Coal Mine infrared Methane Detector 2.Infrared reflective Detector 3.Methane Detector 4.Infrared Detector

Product Introduction

Infrared Methane Sensor is used for detecting methane content in the air of coal mines underground and it is flameproof and Intrinsic Safety type. The sensor is an intelligent detection instrument with infrared remote control functions of zero setting, accuracy adjusting,and alarm point setting and with advantages of stable reliability and flexible use. The sensor has outputs of multiple standard systems, and can be used with all mine-used safety monitoring and control systems, locking devices of air-door, electricity and methane, and power breaking instruments for methane.
