Endura AZ20 series probe
Combustion oxygen monitor
Measurement made easy
Introduction
The Endura AZ20 is the latest in a long line of high-
quality, combustion gas analyzers from ABB.
The sensor, based on a zirconium oxide cell, is
mounted at the tip of the probe that is inserted in
the flue duct. The resulting direct, in situ
measurement provides accurate and rapid oxygen
reading for combustion control / optimization and
emissions monitoring purposes.
Endura AZ20 has been designed for extended
periods of maintenance-free operation. The
modular design with reduced component count
improves the reliability and robustness of the
system and simplifies breakdown repair if it occurs.
Kits containing all the parts needed to complete on-
site repairs are available from ABB, ensuring that
service personnel can effect repairs quickly and
efficiently at minimum cost. The Endura AZ20 probe
has retained an easy-access cell arrangement,
similar to the proven ZFG2 probe. This ensures cell
replacement can be carried out on-site using readily
available, basic hand tools, even after long periods
of high temperature operation.
