  • Electrode with sealing assembly and fill hole cover
    Patent number: 4770762
    Abstract: An assembly is shown over the top portion of the outer body 14 of a reference electrode or combination pH/reference electrode. An element 50 such as a turning ring covers the fill hole 16 through the outer body 14. In one position of the element 50, a sealing element 24 such as an O-ring forms a passage between fill hole 16 and a through hole 52 through element 50. In other positions of element 50, the sealing element 24 seals the fill hole 16. In embodiments shown, a housing 30 is integral with the cap assembly (60, 70) and aligns the sealing element 24 over the fill hole 16.

  • Combination pH/reference electrode with improved temperature response
    Patent number: 4608148
    Abstract: A combination pH/reference electrode is provided with the two electrochemical references being symetrically thermally insulated from the sensing membrane and being thermally adjacent each other. The portion of the pH fill buffer in contact with the inner surface of the sensing membrane is thermally insulated, as by KCl crystals, to rapidly equilibrate in temperatures with the sample solution.
