More Information
Summary: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.
