Shop for Gas Detectors

wonkee donkee science experiments Several gas detection technologies are used in combustible gas detectors. The most common are catalytic bead and infrared detectors.

Catalytic detector

catalytic bead gas detector sensor A catalytic sensor uses temperature changes caused by a combustible gas reacting with oxygen to measure gas levels.

Infrared detector

infrared gas detector sensor An infrared sensor works on the principle that gas will absorb infrared radiation. There will be a sample cell and a reference cell, which are compared to determine the presence of gas.
