Infrared methane alarm detector
Infrared methane gas alarm detector
CH4 alarm,CH4 detector

Summary

JH-100 infrared methane alarm detector is in compliance with minig products certifiction,it is mainly applied in coal mine,natural gas,CBM(Coal bed methane),rubbish filling,sewage treatment,anaerobic fermentation and other field for methane gas leakage detection.

Adopting Infrared gas filter technique,ch4 measurement can not be interfered by other gas compositions.
