ABSTRACT:
Disclosed is a gas measuring device which comprises compensation of disturbances and offers high accuracy of measurement immediately after being activated. Said gas measuring device is provided with a gas sensor (1) for generating a measuring signal (S1) that depends on the gas concentration and can have a spurious component while a high-pass filter (13) having an adjustable limiting frequency is mounted downstream of said gas sensor (1). The limiting frequency can be predefined according to the spurious component by means of a selection unit.
