Continuous Water Quality Monitoring of H2O2

ATi’s Q46/84 Hydrogen Peroxide Water Quality Monitor is designed to continuously measure the concentration of H2O2 in aqueous systems. Using a direct peroxide sensor, the unit responds rapidly to changes in concentration, enabling operators to control chemical feed to maintain specific targets. With both digital and analog communications available, the Q46 is adaptable to a wide variety of peroxide monitoring applications.

The Q46/84 sensors are capable of operating over a fairly broad concentration range, from a low range of 0-2 PPM up to a high range of 0-200 PPM.
