Product profile:
Residual chlorine / chlorine dioxide sensor, using the advanced constant voltage principle, is used to measure the residual chlorine / chlorine dioxide in the water body. This method utilizes the application of a stable potential potential between the polarized electrode and the reference electrode, and different measured components produce different current strengths at this potential. The instrument calculates the concentration of the measured components by collecting and analyzing the current signal.The residual chlorine / chlorine dioxide electrode is simple in structure and easy to clean and replace. Meanwhile, the electrode does not need to replace the diaphragm and reagents, and the maintenance is simple to ensure the stability, reliability and accuracy of the instrument for long-term work.
Typical applications:
For residual chlorine / chlorine dioxide measurement in water plant, drinking water distribution network and swimming pool.
