Type 8232 - Chlorine Sensor

Type Description

The 8232 from Bürkert is an electrochemical sensor designed for the measurement of the free and total chlorine concentration generated from inorganic sources (chlorine gas, sodium hypochlorite solution,...). Type 8232 offer a range of four models: • the “Trace” chlorine sensor (zero-chlorine) with three electrodes is suitable for the measuring of free chlorine at very low concentrations. The membrane of this sensor is protected against biofouling. The sensor works in water without chlorine up to four weeks. It is available with a voltage output on a four-pin fixed connector. • the free chlorine sensor with three electrodes has a sensor with greatly reduced pH-dependency. This model delivers a current output on a M12 connector and is designed to be used in a swimming pool, drinking or sea water. The fluid must contain a minimum chlorine concentration (≥ 0.1 ppm). • the free chlorine sensor with two electrodes delivers a current output on a M12 connector. It is designed to be used using in a swimming pool, drinking or process water. The fluid to be measured must not contain any surfactants or abrasive particles and its pH value must be at a constant level. The fluid must contain a minimum chlorine concentration (≥ 0.1 ppm). • the total chlorine sensor with three electrodes is a sensor with greatly reduced pH-dependency. This model delivers a current output on a M12 connector and is designed to be used in a swimming pool, drinking or sea water, brine. It measures total chlorine = free chlorine + bound chlorine.
