Combustion gas oxygen monitor
in-situ combustion gas oxygen monitor designed to measure excess O₂ in flue gases.
Product Description
The ABB Endura AZ20 is built for optimization and emissions monitoring, it utilizes a zirconium oxide sensor cell at the tip of a probe to provide rapid, direct readings in high-temperature processes.
