ABSTRACT:
An electrochemical sensor with at least one measuring electrode (3), at least one auxiliary electrode (7) and at least one reference electrode (5), wherein a protective electrode (6), which ensures at the reference electrode (5) the at least partial shielding of the reference electrode (5) against substances that would lead to a change in the reference potential when reaching the reference electrode (5), is arranged in the vicinity of the reference electrode (5). A highly stable reference potential can be obtained with the present invention.
