Methane Gas Alarm

Methane gas detectors monitor methane concentration in the air through catalytic combustion or infrared principles, triggering audible and visual alarms when the concentration exceeds preset thresholds. They are used in locations with methane leakage risks, such as gas pipelines, chemical plants, and coal mines, to ensure personnel safety.
Selection
When selecting, ensure the detection range covers 0–100% LEL, with explosion-proof certification and audible-visual alarm functions. Choose between fixed or portable models based on the installation environment, taking into account sensor lifespan and calibration intervals. Check whether the product includes data logging and self-diagnostic fault detection capabilities.
