型号描述

Bürkert 公司的 8232 是一种电化学传感器，用于测量来自某个无机源的游离氯的含量（氯气、次氯酸钠溶液等）。 型号 8232 具有三种结构类型：具有三个电极的氯轨迹传感器（订货号 565164），适合在非常低的浓度下测量氯含量。传感器的隔膜受生物污垢的影响较小。传感器能够一个四极插头（带电缆的插头必须单独订购）上，提供一个电压输出信号。 • 带有三个电极的氯传感器（订货号 566052），具有非常小的 pH 值依赖性。 传感器能够在一个带有电缆接头的二子上，提供一个电流输出信号，这种结构适合游泳池水、饮用水或海水。液体的氯浓度必须控制在最小 ( 0.1 ppm)。 • 带有两个电极的氯传感器（订货号 566051），能够在一个带有电缆接头的二子上，提供一个电流输出信号。 此传感器的适用范围包括游泳池水、饮用水或者与饮用水特性相似的工艺水。 测量液体不得含有清洁剂（例如表面活性剂）或磨损性成分。pH 值必须保持恒定。液体的氯浓度最小必须达到 ( 0.1 ppm)。

1）带有三个电极的跟踪传感器，适合在低浓度条件下进行测量
2）配有三个电极的氯传感器，pH 依赖性大幅降低
3）配有两个电极的氯传感器

Type Description

The 8232 from Bürkert is an electrochemical sensor designed for the measurement of the free chlorine concentration generated from inorganic sources (chlorine gas, sodium hypochlorite,...). The Type 8232 offer a range of three models: • the Cl-trace sensor (Item no. 565164) with three electrodes, is suitable for the measuring of chlorine at very low concentrations. The membrane of this sensor is less affected by biofouling. It is available with a voltage output on a four-pin fixed connector (connector with cable has to be ordered separately). • the chlorine sensor (Item no. 566052) with three electrodes, has a sensor having a greatly reduced pH-dependency. This model delivers a current output on a two-pin terminal through a cable glａnd 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 chlorine sensor (Item no. 566051) with two electrodes, delivers a current output on a two-pin terminal through a cable gland. It is designed to be used using in a swimming pool, drinking or process water having similar qualities as drinking 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).

1）Trace sensor with three electrodes for measurements at low concentrations
2）Chlorine sensor with three electrodes and greatly reduced pH dependency
3）Chlorine sensor with two electrodes
