Flue Gas Probes
General Information
ZIROX flue gas probes (SS31) are robust sensors which serve the λ-determination in large-scale firing plants as well as the measurement of oxygen partial pressure of furnace atmosphere.
The probes are calibration-, drift- and maintenance-free. During measurements in reducing atmosphere, a falsification of the gas composition caused by cooling of the measuring gas in a suction line does not occur. An integrated heater provides the working temperature. The use of high-quality components and materials guarantees high long-term stability.
