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.
