Application:
GJH4 (A) Infrared CH4 Meter can continuously and automatically convert down hole CH4 concentration into a standard electrical signal and then transmit to the matching equipments. It can show the concentration of methane in situ and it has the function of transfinite audible and visual alarm. It can connect with monitoring system, breaker and wind power gas lock instruments. It is widely used in the field of coal mining working face, electrical and mechanical cavern and return air roadway.

Key Feature:
1.It adopts new type single chip microcomputer and high integration digital circuit. Then the circuit structure is simple. Performance is reliable. Easy to maintenance and debugging.
2.It has the function of Infrared remote calibration zero, sensitivity and emergency alarm. It is simple and convenient to calibrating.
3.The sensor has extra function of cutting off control. You can set cutting off point arbitrarily. It has a multi-usage function.
4.Using new type of switching power, reduce the power consumption of the engine, increase the transmission distance of the instrument.
5.Self-diagnostic function, easy to use and maintain.
6.Newly high-strength shell structure, enhance the impact resistance of the instrument.
