Product Overview

ATI Monitoring

The Q46H/64 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 semi-conductor, 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.

ATI’s Model Q46H/64 Dissolved Ozone Monitor provides an economical and reliable measurement system for water quality monitoring and controlling ozone treatment systems. With a variety of outputs including 4-20 mA analog, PID control, three adjustable relays, and digital communications, the Q46H/64 is adaptable to any ozone application.
