Product Description

Residual Chlorine Sensor for Wastewater Treatment

Operation principle

     The online residual chlorine analyzer employs a three-electrode amperometric method. This method utilizes current changes caused by chemical reactions on the electrodes to measure residual chlorine concentration in water samples, with the generated current being proportional to the residual chlorine concentration.

     The three-electrode amperometric measurement system consists of a anode, a reference electrode, and an auxiliary electrode (or counter electrode). During the measurement process, hypochlorous acid (HOCl) selectively permeates through the microporous membrane of the electrode cap into the electrode interior, where it undergoes an electrochemical reaction with the metal electrode to generate a current signal. Under stable conditions, this current signal is directly proportional to the residual chlorine concentration in water.

Features

1.The analyzer features a three-electrode system enabling long-term stable operation;

2. Integrated temperature sensor for real-time thermal compensation;

3. RS485 signal output with strong anti-interference capability (transmission range ≤500m);

4. Open-source communication protocol for device integration and networking;

5. Easy operation,supports software online upgrade;
