B&D DISSOLVED OZONE MONITOR

Water treatment processes using ozone gas have steadily increased over the past 20 years. Ozone has proven to be an extremely effective oxidant, removing organic carbon from raw water and destroying most pathogens. As a result, ozone treatment is now widely used in the semiconductor, pharmaceutical, and food and beverage industries. In addition, many large cities are now using ozone to improve the quality of the drinking water distributed to their customers.

B&D Dissolved Ozone Monitor provides an economical and reliable measurement system for water quality monitoring and controlling ozone treatment systems.

The instrument provides:
– measuring display in the range stated by the installed sensor;
– automatic measurement control function
– alarm from the low/high measurement, the setpoint overtime operation, and the logic input;
– programmable dual analog output for recording and acquisition of the measurement values or PID regulation;
– hold/alarm function activated by two external volt free contacts;
– automatic /manual auto clean function.
