    In most electrochemical measurements it is necessary to keep one of the electrodes in an electrochemical cell at a constant potential. This so-called reference electrode allows control of the potential of a working electrode (e. g. in voltammetry) or the measurement of an indicator electrode (e. g. in potentiometry see Chap. II.9).
