Methane Gas Monitor

Methane gas detectors detect the concentration of methane in the air through catalytic combustion or infrared absorption principles. When methane comes into contact with the sensor, it generates changes in electrical signals or absorbs specific wavelengths of infrared light. The instrument then converts these signals into concentration readings. It is used in applications such as natural gas pipeline inspections, coal mine safety monitoring, and landfill leakage detection.
Selection
When selecting, ensure that the detection range covers 0-100% LEL, and the explosion-proof rating meets the requirements of the operating environment. Prioritize catalytic combustion principle for lower explosive limit detection, and infrared principle for high-concentration or oxygen-deficient environments. Pay attention to sensor lifespan and calibration cycles. For portable devices, consider battery life; for fixed installations, evaluate signal output methods.
