A potentiometric sensor having a measuring half cell with a conductor element, a reference half cell with a reference element, a measuring circuit connected with the conductor element of the measuring half cell and the reference element of the reference half cell and designed to create a measuring signal that is dependent on a potential difference between the conductor element and the reference element. The measuring half cell further includes a housing having a housing chamber closed off by a first ion-selective membrane and contacted by the conductor element, a first inner electrolyte contained within the housing chamber and contacting the ion-selective membrane. The conductor element includes an inner conductor, especially an inner conductor comprising a metallic conductor, connected with the measuring circuit and a gas-tight barrier separating the inner conductor from the first inner electrolyte.

Potentiometric sensor

The disclosure includes an electrochemical half-cell including: a housing; a potential sensing element at least arranged on some segments inside the housing and connected electro-conductively with an electrical contact point outside the housing; and an electrolyte arranged inside the housing, wherein a plurality of hollow bodies is embedded in the electrolyte, especially distributed evenly inside the volume filled by the electrolyte.
