Specifications

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.).
