Description
The instrument is composed of signal measurement, operation, display and panel instructions. The instrument uses the negative voltage of a specific voltage amplitude between the polarized electrode and the reference electrode to select the residual chlorine in the reaction, so that the electrochemical reaction occurs at the cathode of the electrode, thus forming a current signal proportional to the residual chlorine concentration. The instrument calculates the concentration of residual chlorine by collecting and analyzing of current signal, so the instrument has strong selectivity, no replacement parts, small maintenance; long electrode life and high reliability.
