Abstract
A reference electrode for potentiometric measurements has a housing () with a hollow space () containing a liquid reference electrolyte () as well as a conductor element () immersed in the reference electrolyte. In addition, the housing has a diaphragm () through which the reference electrolyte can be brought into contact with a measuring medium () outside of the housing. Furthermore, means are provided to effect an outflow of the reference electrolyte through the diaphragm. A first electrical contact element () 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 () of the reference electrolyte does not fall below a threshold value (F), and that the contact element is not immersed in the reference electrolyte if the fill level falls short of the threshold value.
