A measuring sensor (1) includes a chamber (4), provided with a wall (16) made of a dielectric material, flow connections (5, 6) in this wall for carrying therethrough a gas mixture to be analyzed into (G.sub.1) and out of (G.sub.2) the chamber at a pressure (P) equal to that of ambient air, electrodes (2, 3) on the opposite sides of the chamber with a high alternating voltage (U) applied therebetween, and at least one window (8) in this wall, which is transmissive to wavelengths to be measured. In addition, the sensor includes a light detector element (12) for measuring the intensity of a radiation coming through the window. Said high alternating voltage (U) has a frequency which is at least in the order of 10 kHz for generating in a gas mixture (G) a radiation emission based on the non-ionizing excitation of molecules and/or atoms. The measuring arrangement of the invention includes a measuring sensor operating on some other measuring principle, which produces a signal for analyzing at least one other gas component included in the gas mixture by using a computing unit. The measuring values can be output separately or used for checking the analyzing results received from various measuring sensors and, if necessary, for effecting corrections to the results.
