product name :PDCL-400 Residual Chlorine Online Analyzer
PDCL-400 residual chlorine adopts advanced principle of constant voltage to measure residual chlorine in water.The principle is adding a stable electric potential between polarized electrode and reference electrode to make different measured components produce different current intensity.The analyzer calculates the concentration of the measured component by collecting and analyzing current signal.
PDCL-400 residual chlorine has simple structure,easy to clean and replace.Meanwhile,the electrode dosen’t need to replace membrane and reagent when operating and the maintenance is simple to ensure the stability,reliability and accuracy of instrument for long-term working.
Applications :
- Residual chlorine measurement of waste water and water treatment of water plant,drinking water distribution network,swimming pool and hospital and etc.
