Abstract

A gas measuring device () and a gas measuring process measure a concentration of a target gas. A detector detection variable sensor () measures a detection variable (U) of a detector, which detector detection variable correlates with the concentration of the target gas in a gas sample (Gp). A compensator detection variable sensor () measures a detection variable (U) of a compensator, wherein this compensator detection variable correlates less with the target gas concentration. The gas measuring device can be operated in a pressure-compensating mode and/or in a humidity-compensating mode. In pressure-compensating mode, the influence of the ambient pressure on a measurement result is compensated as best as possible under the boundary condition that the influence of the ambient humidity remains sufficiently small. In humidity-compensating mode, the influence of the ambient humidity on a measurement result is compensated as best as possible under a corresponding boundary condition.
