Rosemount™ 6888 In Situ Oxygen Analyzer

Rosemount

The 6888 combustion flue gas transmitter provides a continuous, accurate measurement of the oxygen remaining in flue gases coming from any combustion process. Accurate measurements of furnace exhaust excess oxygen is critical for combustion optimization, resulting in reduced energy costs, increased safety, and lower emissions. Reduction of overall downtime and maintenance can be achieved with the 6888’s robust oxygen sensor and autocalibration capabilities.
