  • Measuring probe for potentiometric measurements, method of monitoring the state of aging of the measuring probe, and use of the measuring probe
    Patent number: 6685807
    Abstract: A measuring probe for potentiometric measurements has a housing (2) of an electrically insulating material surrounding an enclosed space (4). Inside the space (4) are a primary reference element (6), a secondary reference element (8), an electrolyte (10), and an ion-permeable, micro-porous, high-viscosity polymer substance which, in combination with the electrolyte (10), forms a filler mass (16). The housing (2) has at least one opening (12) to the outside, through which the electrolyte (10) can be brought into contact with a sample solution on which a measurement is to be performed. The secondary reference element (8) is arranged so that the boundary (52) of an electrolyte-deficient region (54) advancing over time from the opening (12) towards the primary reference element (6) arrives at the secondary reference element (8) before reaching the primary reference element (6).
