Basic Information

Detailed Description	The catalytic element works based on the principle of catalytic combustion effect. It consists of two arms of a bridge composed of a detection element and a compensation element. When a flammable gas is encountered, the resistance of the detection element increases, and the output voltage of the bridge changes. This voltage change increases proportionally with the increase of gas concentration. The compensation element serves as a reference and provides temperature and humidity compensation.
Main Applications	It can be used for leak alarms or concentration detection of flammable gases such as natural gas, liquefied petroleum gas, and coal gas in households.
