Products: Handheld Infrared Methane Gas Detector—JHB Series |
|
Category: Gas Detector |
|
Introdutions
JHB series infrared methane alarm detector is in compliance with mining products certification, it is mainly applied in coal mine, natural gas, CBM (Coal bed methane), rubbish filling, sewage treatment, anaerobic fermentation and other fields for CH4 gas leakage detection. Infrared gas filter technique, CH4 measurement can not be interfered by other gas compositions.
Applications
Portable CH4 detector is an ideal instrument with alarm function to detect the concentration of CH4, such as chemical industry, oil & gas storage, mine, metallurgy, liquefied gas station, spray paint, petroleum, fuel gas transport, as well as the leakage of nature gas.
