Claim Text:
1. A water analysis sensor electrode for determining an analyte in water, the water analysis sensor electrode comprising: a sensor electrode housing which is configured to be closed, the sensor electrode housing comprising an inner wall and an ion-selective sensor electrode diaphragm arranged at a lower distal end of the sensor electrode housing; an electrolyte solution in the sensor electrode housing; a measuring electrode arranged in the sensor electrode housing; a gas bubble enclosed by the sensor electrode housing; and a rigid rod element having a round cross section arranged in the sensor electrode housing so that a continuous open capillary channel extends in a straight line over a length of the sensor electrode housing between the rigid rod element and the inner wall, the continuous open capillary channel being provided by the rigid rod element abutting against the inner wall of the sensor electrode housing via adhesion forces, the rigid rod element being made of glass, a metal, a ceramic or a plastic; wherein, the rigid rod element and the sensor electrode housing are not integral with each other.
