Abstract
Electrochemical measuring electrodes often have a thin foil-shaped membrane, e.g. made of a plastic foil, which is arranged at one end of a cylindrical portion of the electrode and maintained in position by means of a resilient ring-shaped member, e.g. an O-ring, which presses the folded-over edge portion of the membrane against the outside of the cylindrical portion. It is now suggested to guide the ring-shaped holding member in such a way on the cylindrical portion that it protrudes beyond the membrane and thereof. The guiding may be provided by means of a circumferential groove in the cylindrical portion near the membrane end thereof.
