Product introduction

Catalytic combustion sensor MC109 product description
-
The MC109 catalytic element operates on the principle of catalytic combustion effect, consisting of a detection element and a compensation element paired to form two arms of a bridge. When exposed to combustible gas, the resistance of the detection element increases, causing a change in the bridge output voltage. This voltage change increases proportionally with gas concentration. The compensation element provides reference and temperature/humidity compensation.
