A device for the coulometric determination of water by a Karl Fischer reaction comprising a membrane-free measuring cell that contains a liquid reagent, an iodine indicating means, an anode, a cathode and a casing around the cathode to define a cathode space. The casing has an opening through which the cathode space communicates with the liquid reagent. A maneuverable drainage device including a plunger is provided to drain-off liquid reagent in the cathode space through the opening.
