Title (DE) REFERENZELEKTRODE
(EN) REFERENCE ELECTRODE
(FR) ÉLECTRODE DE RÉFÉRENCE
Abstract:
(DE) Referenzelektrode, insbesondere für eine potentiometrische Messzelle, umfassend: ein Gehäuse, welches einen Gehäuseinnenraum umgibt, welcher einen Referenzelektrolyten und mindestens einen Teil eines Ableitsystems zum Ableiten eines Potentials der Referenzelektrode enthält, wobei der Referenzelektrolyt mit einem das Gehäuse umgebenden Medium, insbesondere einem Messmedium, über mindestens eine durch eine Gehäusewand des Gehäuses durchgehende Bohrung in Kontakt steht, wobei die Bohrung an ihrer engsten Stelle einen Innendurchmesser von nicht mehr als 50 μm, und eine Längserstreckung von nicht mehr als 200 μm aufweist.
(EN) Reference electrode, in particular for a potentiometric measuring cell, comprising: a housing which surrounds a housing internal space which contains a reference electrolyte and at least one part of a deriving system for deriving a potential of the reference electrode, wherein the reference electrolyte is in contact with a medium, in particular a measurement medium, which surrounds the housing, via at least one hole which passes through a wall of the housing, wherein the hole has an internal diameter of no more than 50 μm and a longitudinal extent of no more than 200 μm at the narrowest point thereof.
(FR) Électrode de référence, notamment pour un potentiomètre, comportant un boîtier entourant un espace intérieur qui contient un électrolyte de référence et au moins une partie d'un système de dérivation destiné à dériver un potentiel de l'électrode de référence, l'électrolyte de référence étant en contact avec un milieu entourant le boîtier, notamment un milieu de mesure, par l'intermédiaire d'au moins un orifice qui traverse une paroi du boîtier. L'invention est caractérisée en ce que l'orifice, en son point le plus étroit, a un diamètre intérieur ne dépassant pas 50 μm et une étendue longitudinale ne dépassant pas 200 μm.
