Methane Detector

Methane detectors operate based on the principles of catalytic combustion or infrared absorption. When methane contacts the sensor, it generates changes in electrical signals or absorbs specific wavelengths of infrared light, which are then converted into concentration readings through circuitry. They are used to monitor methane leaks in natural gas pipelines, mines, landfills, and other locations to ensure operational safety.
Selection
When selecting, consider a detection range covering 0-100% LEL, with a resolution of 1% LEL, and equipped with audible and visual alarm functions. Determine the explosion-proof rating based on the usage environment. For fixed installations, ensure compatibility with the control system, while for portable devices, prioritize battery life. Regular calibration is essential to ensure data accuracy, and prioritize models with a response time of less than 15 seconds.
