Membrane or constant-voltage measurement tracks hypochlorous acid and free chlorine from 0.00 to 20.00 mg/L with ppb-level resolution. Automatic temperature compensation, IP68 protection, flexible installation, and RS485 output support precise chlorination control.
The membrane method is reagent-free, while the constant-voltage design uses a stable dual-platinum ring. Both provide ppb-level resolution for accurate, closed-loop chlorination with lower chemical use.
