Y535-A Free Chlorine Sensor
Description
Yosemitech Y535-A Free Chlorine Sensor uses a negative pulse of specific voltage amplitude applied between the polarized electrode and the reference electrode to selectively select free chlorine to participate in the reaction, so that it can undergo an electrochemical reaction at the cathode of the electrode, thus forming a current signal proportional to the concentration of free chlorine. The Free Chlorine Meter calculates the concentration of free chlorine by collecting and analyzing the current signal, so the meter has the characteristics of strong selectivity, no need to replace parts, small maintenance, long electrode life and high reliability.
