Abstract
A gas measuring device () and a gas measuring process measure a concentration of a combustible target gas (CH). A detector (), having a detector heating segment (), oxidizes combustible target gas. A compensator () having a compensator heating segment () oxidizes less or no target gas. A temperature sensor () measures the ambient temperature. A first detection variable (ΔU_B) depends on the detector temperature, a second detection variable (U) depends on the compensator temperature. An evaluation unit () applies a first and a second functional relationship in order to determine, depending on the two detection variables (ΔU_B, U), both the target gas concentration and a further environmental condition, particularly the ambient humidity. The second functional relationship, a dependence between the further environmental condition on the one hand and the detection variables and the ambient temperature on the other hand, is valid if no target gas is present.
