ABB's Endura Combustion Gas Oxygen Analyzer AZ20 offers high quality oxygen level measurement and monitoring, for a better overall emissions analysis and combustion control maximization, just like all of ABB's line of oxygen analyzers do. This high quality of oxygen level analysis is all thanks to the Endura Combustion Gas Oxygen Analyzer AZ20s zirconium oxide cell-based sensor is perched at a probe's tip (probe enables temperature processing up to a maximum of 1,472 degrees Fahrenheit), which, in turn, is embedded into a flue duct. The flue duct, the probe, the sensor, and the whole analyzer as well, have all been meticulously designed to be sturdy and long-lasting. This robust design plan is only one of many more of the Endura Combustion Gas Oxygen Analyzer AZ20's many features.
