Contamination Resistant Low Conductivity Three Electrode Total Chlorine Sensor For Drinking Water Or Swimming Pool

 

The three-electrode membrane total chlorine sensor is a type of sensor commonly used for water quality monitoring. It adopts a three-electrode design and the membrane method measurement principle. It consists of a working electrode, a reference electrode and a comparison electrode.

The working electrode is responsible for detecting chloride ions in water samples, the reference electrode provides a stable potential as a reference, and the contrast electrode is used to calibrate and compensate for the effects of changes in temperature, pressure, etc. in the environment on the measurement results.

 

The working principle of the sensor is based on the reaction of chloride ions in water. The working electrode is covered with a selective chloride ion sensing membrane. When chloride ions come into contact with this membrane, it will cause a charge change. The concentration of chloride ions is determined by measuring the current between the electrodes, thereby indirectly determining the concentration of chloride ions in the water sample. Total chlorine content.

 

The three-electrode membrane total chlorine sensor sensor has the advantages of fast response, high sensitivity, and good reliability, ensuring that water quality meets safety standards.

Information about themeasuring range

The actual slope of a sensor can vary production-related between 65% and 150% of the nominal slope

Note: With a slope > 100% the measuring range is reduced accordingly.

(Ex.: 150% slope → 67% of the specified measuring range)
