Methane concentration measuring instrument

Methane concentration detectors measure gas levels using catalytic combustion or infrared absorption principles. When the sensor comes into contact with methane, it generates an electrical signal or absorbs infrared light at specific wavelengths. These devices are used for leak detection and safety warnings in locations such as mines and chemical plants.
Selection
When selecting, consider that the detection range covers the on-site methane concentration, the response time meets safety requirements, the explosion-proof rating matches the environment, the sensor lifespan and calibration cycle affect maintenance costs, and the choice between portable or fixed types is determined based on installation needs.
