CLDS710 Digital Residual Chlorine Sensor Electrode principle characteristics:

Constant voltage principle electrode is used to measure residual chlorine or hypochlorous acid in water. The constant voltage measurement method is to maintain a stable potential at the electrode measuring end, and different measured components produce different current intensities under this potential. It consists of two platinum electrodes and a reference electrode to form a micro current measurement system. The residual chlorine or hypochlorous acid in the water sample flowing through the measuring electrode will be consumed. Therefore, the water sample must be kept flowing continuously through the measuring electrode during measurement.

The constant voltage measurement method uses a secondary instrument to continuously and dynamically control the potential between the measuring electrodes, eliminating the inherent resistance and oxidation-reduction potential of the measured water sample, so that the electrode can measure the current signal and the measured water sample concentration A good linear relationship is formed between them, with a very stable zero point performance, ensuring accurate and reliable measurement.

The constant voltage electrode has a simple structure and a glass appearance. The front end of the online residual chlorine electrode is a glass bulb, which is easy to clean and replace. When measuring, it is necessary to ensure that the water flow rate through the residual chlorine measuring electrode is stable.

Residual chlorine or hypochlorous acid. This product is a digital sensor that integrates electronic circuits and microprocessors inside the sensor, referred to as digital electrode.
