When measurements are made in a reducing atmosphere, distortion of the gas composition due to cooling of the measured gas in the suction tube does not occur. Use high quality components and materials to ensure high long-term stability. If the fuel gas composition is known, it is possible to calculate the air factors λ, CO-, CO2-, H2- and H2O- concentrations. These values can be supplied by external electronic components (e.g. ZIROX? Electronic components E2000).

KS20 serves process control and combustion optimization (T? The V-approval was based on "TA Luft, 13. And 17. BImSchV ") for power and thermal power plants as well as incinerators.

It is also a part of oxidation and reduction furnace gas control in the ceramic industry.
