The apparatus for the simultaneous determination of different gas components comprises a multiplicity of electrochemical three-electrode measuring cells with a common electrolyte which are formed by a multiplicity of working electrodes with a common counter-electrode and a common reference electrode. The measured value is produced with the aid of a potentiostatic analysis circuit which also adjusts and defines the potentials at the working electrodes. The current signals correlated with the gas concentrations to be measured are indicated with the aid of ammeters 111..11n in the lines to the working electrodes 51..5n. In doing so, it is essential that all the three-electrode measuring cells have a common counter-electrode 3 and a common reference electrode 4 and that the potentiostatic analysis circuit 6 has control circuits 71..7n which keep the potentials of the working electrodes 51..5n relative to the reference electrode 4 constant, individually and independently of one another. …<IMAGE>… |
