Residual Chlorine Sensor On Electrochemistry And Measurement Equipment Use Thereof

PURPOSE: An electrochemical type residual chlorine sensor and a measuring device by using the same are provided to instantly use the electrochemical type residual chlorine sensor. CONSTITUTION: An electrochemical type residual chlorine sensor includes an actuating electrode(140), a first electrode member(110), an auxiliary electrode(150), a second electrode member(120), a reference electrode(160), and a flow cell(130). The actuating electrode(140), the auxiliary electrode(150) and the reference electrode(160) are installed in a measurement cell, thereby forming 3-electrode system. The actuating electrode(140) and the auxiliary electrode(150) are made of a platinum disc and the reference electrode(160) includes a saturated calomel electrode. Density of residual chlorine is measured by using the electrochemical type residual chlorine sensor.
