ELECTRODE BODY FOR MEASURING SALINITY CONCENTRATION

摘要

PURPOSE:To provide a disposable electrode body being employed in the measurement of chlorine ion concentration by applying chronoamperometry using a micro silver electrode. CONSTITUTION:A Pd layer and a PbSO4 layer, a reference electrode 5 laminating a dry layer of an SO. ion generating material, a working electrode 4 comprising a plating film of Ag exposing only a predetermined area, and a pair electrode 6 are arranged on a substrate 1. At the time of measurement, SO4 ions are generated from an aqueous solution to obtain a predetermined potential reference. This structure provides a dry maintenance free electrode body and since oxidation/reduction of silver/silver chloride takes place over a previously designed area, an accurate measurement is realized.
