Four corrosion-proof steel tubes are arranged in a circle, two of the steel tubes serving as reference chamber, the other two being serially flown through by a measuring gas. Each cell contains centrally a heating coil of nickel on a PTFE mandrel held by an electrode which is fed through a brazed on ceramic insulation in the top portion of the respective chamber. The other electrode is fed through off center; each electrode is hollow in the feed-through.
