DataStick Aquachlor Chlorine Sensor
- Accurate Results Accuracy delivered between 4-9 pH
Overview
The Thermo Scientific AquaSensors AquaChlor free Chlorine sensor will measure accurately in clean water processes between 4 and 9 pH. Best performance is achieved when used in applications
where process pH, flow, pressure and temperature are stable. When used with the Thermo Scientific AV38 Local Display/Controller and a pH DataStick sensor, measured hypochlorous acid (HOCl) and
hypochlorite ion (OCl-) concentrations can be used to determine free chlorine levels present.
Features of the AquaChlor Monitoring System include an easyto-replace sensor membrane cap, temperature compensation, a turn-key reagent free design and a compact mounting footprint.
For optimum measurement performance the unique flow chamber maintains regulated pressure and flow. The AquaChlor Free Chlorine Monitoring System is also EPA compliant according to Method 334.0.
