Abstract

Ce dispositif qui comprend une électrode de référence 3, une électrode de réduction 2 en métal noble pour l'oxygène, et une membrane de fermeture 6 perméable à l'oxygène, imperméable à l'eau et isolant le dispositif de l'espace extérieur, est caractérisé par le fait qu'une membrane de coordinat 20 contenant un ligand cationique, perméable à l'hydrogène est prévue devant l'électrode de réduction 2, et qu'entre la membrane de coordinat et la membrane de fermeture est placé un électrolyte 5 contenant le cation dn ligand. Utilisation de ce dispositif pour mesurer avec plus de précision les concentrations en oxygène, et prolonger la durée de vie des électrodes.
