Abstract
A combination electrode, including: A first tube; a measuring membrane, which sealedly closes the first tube to form a measuring chamber; a second tube, which surrounds the first tube and is connected borderingly with the first tube to form an annular reference chamber; a buffer solution located in the measuring chamber; an electrolyte solution located in the reference chamber; a first tapping electrode in contact with the buffer solution; and a second tapping electrode in contact with the electrolyte; wherein, additionally, arranged in the reference chamber is an axially shiftable, annular, sealing element, which bounds the volume occupied by the electrolyte solution, the sealing element is biased by means of an electrically conductive, elastic, deformation element, which surrounds the first tube, and the second tapping electrode is electrically connected with the deformation element, in order to tap the potential of the second electrode via the deformation element.
