Abstract

L'invention concerne un électrode de détection de pH, dans laquelle un conducteur en cuivre isolé est clivé pour produire une surface finale propre exposée, et sur laquelle un revêtement d'antimoine est pulvérisé ou évaporé. On réalise la détection du pH en mesurant la différence de tensions entre ladite électrode et une électrode de référence en argent immergée dans la même matière. On utilise l'électrode, par exemple, en tant que cathéter de mesure de la valeur du pH des fluides corporels.
