EEndura AZ25 series probeCombustion oxygen monitorMeasurement made easyIntroductionThe Endura AZ25 Combustion Oxygen Analyzer isthe latest in a long line of high-quality, combustiongas analyzers from ABB. The AZ25 is designed tomeasure oxygen concentration in high temperaturefurnace atmospheres.The sensor, based on a zirconium oxide cell, ismounted at the tip of the probe that is inserteddirectly into the furnace. The resulting direct, in-situmeasurement provides an accurate and rapidoxygen reading, for combustion control /optimization and process quality control purposes.The in situ technique provides a true oxygenmeasurement inside the process. It eliminates‘equilibrium shift’ that is common to systems inwhich gas samples are extracted and cooled beforemeasurement.—Superior technologyand quality from theworld leader in oxygenmeasurement
