Oxygen analyzer O2 – Control

watermonitoringprocess

Online measurement system for continuous monitoring of oxygen content in hot process water With O2 – Control the residual oxygen content of process water in the range of 0.001 mg/l to 0.5 mg/l can be monitored continuously. In a bypass procedure the compact wall unit takes minimal water samples from the process water, determines the oxygen value and evaluated it against preset threshold values. In case of an threshold value exceeding alarm will be signaled. Standardized interfaces offer a variety of integration possibilities in the process. The device can be installed easily in systems of different types. Also a subsequent installation is possible.
