This 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, temperature, flow and pressure 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.
