Abstract
A high temperature-high pressure electrode for electrochemical potential measurement has a high temperature probe comprising an oxidized zirconium alloy tube member having an electroconductive core which includes a liquid electrolyte and a porous plug held in place by an oxidized zirconium alloy tube and end plug with an axial bore extending therethrough. The electroconductive core can comprise a liquid electrolyte of soaked zirconia sand and a second porous plug. In another embodiment, the zirconia sand is replaced by a surface oxidized zirconium alloy rod with grooves which extend between ends for containment of the liquid electrolyte. This embodiment also contains a second porous plug. In a modification of the latter embodiment, there is a bore in the proximal end of the surface oxidized rod which communicates with the grooves to provide electrical continuity. A Teflon sleeve forms an annular seal between the proximal end of the oxidized rod and the oxidized tube.
