Abstract
A gas detection device () and a gas detection process are configured to detect the presence of a combustible target gas in a gas sample and/or to measure the concentration of the target gas in the gas sample. A detection arrangement (DA) includes at least two detectors (, . . . ) and at least one compensator (). This forms two different detector-compensator pairs (P., . . . ). A compensator belongs to two different pairs. Each pair can be switched on and off independently of any other pair. Only one pair is switched on at any time. A heated detector (, . . . ) oxidizes combustible target gas. A measuring unit measures a detection variable for each pair. An evaluation unit () derives the target gas concentration from the detection variable. During operation, each pair is switched on one after the other, the respective detection variable is measured and the pair is switched off again.
