Micro GC Coal Mine Gas Analyzer

Gas detection in the coal mine industry is critical to ensure protection from the hazardous gases generated in the mining environment.

Gases that should be monitored include permanent gases, such as hydrogen, carbon monoxide, methane, C2 to C3 hydrocarbons, hydrogen sulfide, and SF6. Among them, the concentration changes of hydrogen, methane, and C2 light hydrocarbons can indicate whether there is an explosion risk.

The inhalation of CO and H2S threatens the health and safety of miners.
