The Endura AZ25 is a zirconium oxide-based oxygen analyzer for in-situ measurement in high-temperature combustion processes up to 1,400 °C. It features probe insertion lengths from 556 mm to 1,251 mm with sheath options in aluminous porcelain, recrystallized alumina, or Incoloy 800. The remote transmitter operates at -20 to 55 °C in an IP66 (NEMA 4) enclosure, with standard 4-20 mA output and dual 5 A relay contacts. It includes integrated automatic calibration with test gas detection, HART communication, and supports reference air flow of 0.3 to 0.5 L/min. Maximum sensor-to-transmitte
The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted into the furnace or flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion optimization, process control and furnace atmosphere monitoring.
