Abstract

A water analysis sensor electrode for determining an analyte in water includes a sensor electrode housing which is configured to be closed. The sensor electrode housing comprises an inner wall and an ion-selective sensor electrode diaphragm arranged at a lower distal end of the sensor electrode housing. An electrolyte solution is in the sensor electrode housing. A measuring electrode is arranged in the sensor electrode housing. A gas bubble is enclosed by the sensor electrode housing. A rigid rod element having a round cross section is arranged in the sensor electrode housing so that a continuous open capillary channel extends over a length of the sensor electrode housing between the rigid rod element and the inner wall.
