Abstract

L ' invention concerne une cellule de mesure de potentiel qui comprend un corps (56) qui délimite une cavité (58) et une ouverture (60) par laquelle la cavité débouche à l'extérieur du corps, un pont ionique (61) disposé dans l'ouverture (60) du corps et fermant la cavité (58) de manière étanche, une électrode témoin (62) formée d'acier, disposée dans la cavité (58) et reliée électriquement à l'extérieur du corps par un conducteur (64) d'électrode témoin, une électrode de mesure (66), disposée dans la cavité (58) et reliée électriquement à l'extérieur du corps par un conducteur (68) d'électrode de mesure, et un milieu conducteur ionique non solide disposé dans la plus grande partie de la cavité (58) au moins, au contact des électrodes témoin et de mesure (62, 66). Application à la protection cathodique.
