  • Page 18: Technical Information

    TECHNICAL INFORMATION Operating Principle The ChloroSense uses the electrochemical technique known as chronoamperometry. Chronoamperometry involves applying a fixed voltage to a working electrode and recording the resulting current-time dependence. The magnitude of the current is directly proportional to the concentration of chlorine in the test sample. ChloroSense sensors have two working electrodes, one that measures free chlorine and one that measures total chlorine.
