Measurement principle

The instrument consists of signal measurement, calculation, display, and panel commands. This instrument uses a negative voltage of a specific amplitude applied between the polarized and reference electrodes to selectively select residual chlorine for the reaction, causing an electrochemical reaction at the cathode of the electrode, thereby generating a current signal proportional to the residual chlorine concentration.

The instrument calculates the concentration of residual chlorine by collecting and analyzing current signals, making it highly selective, requiring no replacement parts, and requiring minimal maintenance; Long electrode lifespan; High reliability.
