類型 8232 - Chlorine sensor

類型描述

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 is available in four variants: • The “Trace” chlorine sensor (zero-chlorine) equipped with three electrodes is suitable for the measuring of free chlorine at very low concentrations. 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 on a four-pin fixed connector. • The free chlorine sensor with three electrodes offers greatly reduced pH-dependency. This sensor has a current output on a M12 connector and is designed for applications 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 in a swimming pool, drinking or process water. The fluid to be measured must not contain any cleaning agents (e.g. surfactants) or abrasive particles and its 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 delivers a current output on a M12 connector and is designed for applications in a swimming pool, drinking or sea water, brine. It measures total chlorine = free chlorine + bound chlorine.
