A combination electrode includes a working electrode, a reference electrode, a hydrogel diaphragm, an outer tube and an inner tube. The working electrode is disposed in the inner tube. The reference electrode is disposed in a reference chamber formed between the inner tube and the outer tube. The hydrogel diaphragm seals the opening between an end of the outer tube and the inner tube when the hydrogel swells upon coming in contact with a first electrically conductive fluid that is introduced into the reference chamber. The diaphragm is coupled to the reference electrode in an electrically conductive manner through the first electrically conductive fluid, which contacts both the reference electrode and the diaphragm. The inner tube is closed by a glass membrane that is coupled to the working electrode in an electrically conductive manner through a second electrically conductive fluid that contacts both the glass membrane and the working electrode.

Novel type of electrochemical probe comprising a reference electrode array, each reference electrode comprising a conductor element. The set-up allows for internal calibration as well as being adapted to long storage in dry state. Individual conductive elements of the electrode array do not start to shift/drift, simultaneously but that it is rather individual conductive elements that show deviating behavior. Relatively simple statistical analysis of the respective voltages obtained for the respective conductive elements of the reference electrode array allow identifying such deviating conductive elements, and then take corrective action, such as for example disregarding the measured values provided by such deviating conductive element or regenerating such deviating conductive elements by applying a voltage to re-chlorinate or electrochemical snibbing the surface of such element for cleaning purposes, which can also be done with the respective probe or reference electrode remaining in place, i.e. without for example having to remove the junction element comprising the electrolyte.
