1. Reference electrode arrangement (10) for an electrochemical sensor (100;

  • 200), for a potentiometer, characterized in that it comprises;

    a reference half-cell space having a reference electrode (22),the reference half-cell space comprising a storage space (12) in which a reference electrolyte (24) is provided in at least a storage state of the reference electrode arrangement (10),the reference half-cell space further comprising a lock-out space (14) that is permeable at least with respect to passage of a reference electrolyte (24) into the environment of the reference half-cell space,in the storage state of the reference electrode arrangement (10), the storage space (12) is separated from the lock-out space (14) with respect to the passage of the reference electrolyte (24),the reference electrode arrangement (10) is designed such that a connection can be produced between the storage space (12) and the latching space (14), which connection is permeable for the passage of the reference electrolyte (24) from the storage space (12) to the latching space (14) in order to switch the reference electrode arrangement (10) from the storage state into the operating state;

    the reference electrode (22) extending into the storage space (12);

    the reference half-cell space is formed by a housing;

    the storage space (12) is arranged above the locking space (14) and the two spaces are separated by a horizontal wall, or the storage space (12) is arranged beside the locking space (14) and the two spaces are separated by a vertical wall;

    the reference electrode extends from the top cover of the storage space into the interior of the storage space.
