The Rosemount OCX8800 Oxygen & Combustibles Analyzer for Hazardous Areas provides a continuous, accurate measurement of the oxygen and combustibles remaining in flue gases from the combustion process in hazardous areas. The time-tested and world renowned zirconium oxide sensor is the basis for the oxygen measurement. This, coupled with the combustibles sensor can detect oxygen and combustibles concentrations in flue gases with temperatures up to 2600°F (1427°C).
