AMPEROMETRIC ELECTROCHEMICAL SENSOR AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to an amperometric electrochemical sensor with a fixed potential used in a probe for measuring the content of an oxidation reduction substance dissolved in a liquid, in particular the chlorine content. The sensor (1) includes an insulating substrate (2), a set of electrodes consisting of a working electrode (3), an auxiliary electrode (4) and a reference electrode, at least one of said working electrode (3) and auxiliary electrode (4) being configured on said insulating substrate (2). At least one of said working electrode (3) and auxiliary electrode (4) is covered with an insulating layer (8), said insulating layer (8) including at least one opening exposing at least one of said working electrode (3) and auxiliary electrode (4).
