CA 2169759

A reference electrode for electrochemical measurements made in aqueous solutions under high pressures and at high temperatures. The reference electrode comprises a metallic conductor wire (1), on the surface of said conductor wire, an insulating layer (2) of its own oxide, on the surface of the wire, an area (3) free of insulating layer, and a metal/salt coating (4) covering the area, serving as an electrochemical element determining the potential.

Electrode de référence destinée à des mesures électrochimiques effectuées dans des solutions aqueuses soumises à des pressions et à des températures élevées. L'électrode de référence comprend un fil conducteur métallique (1), sur la surface duquel est appliquée une couche isolante (2) composée de l'oxyde du métal composant le fil, une zone (3) dépourvue de couche isolante, ménagée sur la surface du fil, et un revêtement métallique/de sel métallique (4) recouvrant ladite zone (3), et servant d'élément électrochimique déterminant le potentiel.
