Abstract

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 the working electrode (3) and auxiliary electrode (4) being configured on the insulating substrate (2). At least one of the working electrode (3) and auxiliary electrode (4) is covered with an insulating layer (8), the insulating layer (8) including at least one opening exposing at least one of the working electrode (3) and auxiliary electrode (4).
