ABSTRACT:
A reference electrode for potentiometric measurements has a housing (2) with a hollow space (4) containing a liquid reference electrolyte (6) as well as a conductor element (8) immersed in the reference electrolyte. In addition, the housing has a diaphragm (12) through which the reference electrolyte can be brought into contact with a measuring medium (10) outside of the housing. Furthermore, means are provided to effect an outflow of the reference electrolyte through the diaphragm. A first electrical contact element (20, 36) is arranged in the hollow space in such a manner that the contact element is immersed in the reference electrolyte as long as the fill level (18) of the reference electrolyte does not fall below a threshold value (FS), and that the contact element is not immersed in the reference electrolyte if the fill level falls short of the threshold value.
