摘要： 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.

摘要： A electrochemical sensor for the detection of traces of HF and/or other acid gases in air, comprising a measuring electrode of an electrochemically active metal oxide powder, a reference electrode for fixing the potential of the measuring electrode close to the equilibrium potential of the oxidation/reduction system of MeOn/Mem+, and a counter electrode. The electrodes are in communicative contact with a hygroscopic electrolyte. The measured gas component changes the pH of the electrolyte, and thus the electrochemical equilibrium of the measuring electrode, to produce a measurable electrical current that is proportional to the concentration of the detected acid gas.
