The Q45P/R AutoClean pH/ORP monitor combines differential pH/ORP sensors with the air blast AutoClean system that keeps with sensor clean without manual intervention, enabling operation in locations where contamination and fouling causes standard monitors to fail.

It is designed for al industrial and municipal applications.

The system features a number of diagnostics to alarm the user should an electrode break, the sensor seal integrity fail, the integral air temperature fair or the AirClean system fail.
