Abstract

a. Sonde de mesure pour déterminer la concentration d'ions dans des liquides. b. Cette sonde comprend un corps d'acier tubulaire émaillé comportant une couche extérieure émaillée servant d'électrode de mesure, et dans lequel est logée de façon étanche une électrode de référence dont l'électrolyte est amené au contact du liquide de mesure par l'intermédiaire d'un diaphragme. Elle est caractérisée en ce que l'électrode de référence est constituée par un réceptacle à électrolyte ayant la forme d'un corps cylindrique creux interchangeable en une matière électriquement isolante, telle que le polytétrafluoroéthylène, qui renferme le système d'électrodes de réference et le diaphragme, en ce que le corps d'acier tubulaire n'est émaillé qu'intérieurement dans une région d'extrémité étanchée, et en ce que l'extrémité insérée de ce corps est pourvue d'un contact pour établir une connexion avec l'électrode de référence. c. Conceme les appareillages de laboratoires et en particulier pour déterminer pH de certains liquides.
