Abstract

The present application relates to an electrochemical reference half-cell, in particular, for an electrochemical sensor for measuring a measurand of a medium surrounding the sensor, including a housing with a chamber that is filled with a reference electrolyte and compressed air, wherein the reference electrolyte is in electrolytic contact with a medium surrounding the chamber across a junction in particular, a diaphragm arranged in a wall of the chamber, and a pickup electrode in particular, comprising an electric conductor immersed in the reference electrolyte, wherein the reference half-cell has a measuring device capable of generating an electrical signal that can be traced back to the pressure in the chamber.
