Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Bestimmung und/oder Überwachung des pH-Wertes eines Mediums in einem Behälter durch Messung der Potentialdifferenz zwischen einer pH-Halbzelle (3) und einer Referenzhalbzelle (4), wobei eine Abschirmung (12) aus einem elektrisch leitenden Material vorgesehen ist, und wobei die Abschirmung (12) so ausgestaltet und/oder bezüglich der pH-Halbzelle (3) und der Referenzhalbzelle (4) so angeordnet ist, dass sich äussere Störpotentiale den beiden Halbzellen (3, 4) im wesentlichen gleichwertig und gleichsinnig überlagern.
