pH-Independent Free Chlorine

The 56 is compatible with the 498CL-01 pH-independent free chlorine sensor. The 498CL-01

sensor is intended for the continuous determination of free chlorine (hypochlorous acid plus

hypochlorite ion) in water. The primary application is measuring chlorine in drinking water. The

sensor requires no acid pre-treatment, nor is an auxiliary pH sensor required for pH correction.

The 56 fully compensates free chlorine readings for changes in membrane permeability caused

by temperature. For more information concerning the use and operation of the

amperometric chlorine sensors, refer to the product data sheets.
