5 Best Combustible Gas Detectors - Aug. 2021 - BestReviews

A. Combustible gas detectors typically use one of two technologies to detect gas: catalytic sensors or infrared (IR) sensors. Catalytic sensors are the primary way of detecting combustible gases in these devices. They feature a wire coil that oxides gas and passively reads the resulting resistance in the coil. IR sensors are the more active method. These transmit and receive light several ...
