Background

A flammable gas detector is a detector that responds to a single or multiple flammable gas concentrations. The combustible gas detector has two types, namely a catalytic type and an infrared optical type. The catalytic type flammable gas detector causes oxidation reaction (flameless combustion) on the surface of the platinum wire when the flammable gas enters the detector, and the generated heat raises the temperature of the platinum wire, so that the resistivity of the platinum wire changes. The gas sensor can be divided into a desk type gas detector and a hand-held gas detector according to the use mode, and can be divided into a single gas detector and a plurality of gas detectors according to the quantity of the detectable gas, and can be divided into an infrared gas detector, a thermomagnetic gas detector, an electrochemical gas detector, a semiconductor gas detector, an ultraviolet gas detector and the like according to the principle of the gas sensor.
