Abstract
The device for the simultaneous detection of dissimilar gas components contains a number of electrochemical, three-electrode measuring cells with a common electrolyte, that are formed from a number of working electrodes with a common counter-electrode and a common reference electrode. Measured values are generated with the aid of a potentiostatic evaluation circuit that also adjusts and sets the potentials at the working electrodes. The current signals correlated with the gas concentrations to be measured are displayed with the aid of current-measuring instruments 11.sub.1 . . . 11.sub.n in the lines to the working electrodes 5.sub.1 . . . 5.sub.n. At the same time it is important that all three-electrode measuring cells have a common counter-electrode 3 and a common reference electrode 4, and that the potentiostatic evaluation circuit 6 contains control loops 7.sub.1 . . . 7.sub.n which maintain the potentials of the working electrodes 5.sub.1 . . . 5.sub.n constant with respect to the reference electrode 4, both individually and independently of each other.
