Type Description
Type 8232 from Bürkert is an electrochemical sensor for measuring the free chlorine concentration generated from inorganic sources (chlorine gas, sodium hypochlorite solution, ...). Four variants of Type 8232 are available: • the “Trace” chlorine sensor (zero chlorine) equipped with three electrodes is suitable for measuring very low concentrations of free chlorine. The diaphragm of this sensor is protected against biofouling and can therefore work for up to four weeks in water without chlorine. It has a voltage output at a four-pin plug. • The free chlorine sensor with three electrodes offers greatly reduced pH dependency. The sensor has a current output at an M12 plug and is designed for applications in swimming pool, drinking or sea water. The liquid must contain a minimum chlorine concentration (≥ 0.1 ppm). • The free chlorine sensor with two electrodes delivers a current output on an M12 plug. This sensor is designed for use with swimming pool, drinking or sea water. The fluid being measured must not contain any cleaning agents (e.g. surfactants) or abrasive particles. The pH value must be kept at a constant level. The fluid must contain a minimum chlorine concentration (≥ 0.1 ppm). • The total chlorine sensor with three electrodes offers greatly reduced pH dependency. This sensor has a current output at an M12 plug and is designed for applications in swimming pool, drinking or sea water, brine. It measures total chlorine = free chlorine + bound chlorine.
