Abstract

L'invention concerne un capteur électrochimique, par exemple un capteur électrochimique à électrolyte pour la détection de traces de métaux lourds dans des eaux usées industrielles. Le capteur comprend : un boitier (2) ; une électrode de travail (6) ayant une surface de mesure (62) située à l'extérieur du boîtier, en contact avec un liquide à analyser ; une deuxième électrode (8) ; des conducteurs électriques (20, 22) agencés dans le boîtier pour la connexion des électrodes (6, 8) à un circuit de mesure. Le capteur est caractérisé en ce que l'électrode de travail (6) est portée par un support (4) assemblé de façon amovible au boîtier (2). Grâce au support amovible, le capteur peut être restauré aisément et à moindre coût en cas de dégradation de son électrode de travail, et l'électrode de travail ne risque pas d'être contaminée, car elle peut être dissociée du capteur, lors du changement de l'électrolyte. Figure pour l’abrégé : Fig. 3
