ELECTROCHEMICAL GAS PENETRATION TYPE RESIDUAL CHLORINE SENSOR SUITABLE FOR MEASURING THE CONCENTRATION OF THE WHOLE FREE AND RESIDUAL CHLORINE CONTAINED IN SAMPLE SOLUTION BY MEASURING A CURRENT INPUTTED FROM THE OUTSIDE

摘要

PURPOSE: An electrochemical gas penetration type residual chlorine sensor is provided to enable the immediate use in a field in a short time due to rapid initial stabilization and rapid sensing speed and to stably measure chlorine remaining in sample solution for a long time.;CONSTITUTION: An electrochemical gas penetration type residual chlorine sensor includes a selective residual chlorine penetration film (110), an electrode unit (150), and a cell body unit (160). The selective residual chlorine penetration film penetrates through only free and residual chlorine and no liquid components. The electrode unit is composed of a working electrode (130) causing a current change according to the amount of the residual chlorine penetrated through the selective residual chlorine film; an auxiliary electrode (135); and a reference electrode (140). The selective residual chlorine film, the working electrode, the auxiliary electrode, and the reference electrode are mounted on the cell body unit. The working electrode, the auxiliary electrode, and the reference electrode form three-electrode group structure.;COPYRIGHT KIPO 2013
