Measurement of oxygen concentration in flue gases
Fields of application
Reliable process control for furnaces, metallurgy, semiconductor industry and gas separation.
Benefits
This analyser enables continuous measurement of the oxygen concentration in a gas mixture using the magnetic property of oxygen. Compared with other oxygen measurement systems, the ZAJ-6 offers faster response, and minimal influence of other compounds in the gas mixture. What's more, it's easy to use, thanks to a host of features such as customizable scale settings and intuitive operation. The ZAJ-6 can be used in a variety of sectors (furnace control for heat treatment, combustion furnaces, etc.).
