Emerson's Rosemount Analytical 6888 In Situ Oxygen Analyzer

The 6888 In Situ Oxygen Analyzer is used for integrating an oxygen probe and field electronics into a single, compact package.

The oxygen probe can be directly inserted into a flue gas duct in order to measure oxygen in combustion processes. The 6888 in situ oxygen transmitter is used for measuring oxygen remaining in the flue gases which are emitted during combustion process.

These oxygen measurements can be used in a control system or by a boiler operator in order to alter burner fuel or air ratios for ensuring maximum efficiency with the lowest levels of NO_X, CO and CO₂.

This analyzer is easy to use and integrate. It requires little maintenance as it does not consist of sampling apparatus and moving parts.
