An electrode, particularly a miniature electrode, having structural integrity and reliable electrical operation results. A thin fluoroplastic liner, preferably, a TFE fluorocarbon liner, seals an electrode disc core to a PCTFE fluoroplastic shroud. By properly machining and assembling the electrode disc core, TFE fluorocarbon liner and PCTFE fluoroplastic shroud, a fluid tight interference seal is obtained to avoid the electrolytic fluid leaking into the electrode to corrode the conductive electrical path. A stainless steel spring extends between the electrode disc core and an electrode contact in the PCTFE fluoroplastic shroud to complete the conductive path through the electrode. The spring has two flat ends which are held in reliable surface contact with the disc core and the electrode contact by the bias of the spring itself. The spring thus provides a reliable electric connection with good conductivity.
An electrode for electrically sensing characteristics of electrolytic fluids being tested comprising an electrode disc core, a TFE fluorocarbon plastic liner receiving the electrode disc core assembled therein and sealed thereto, a PCTFE plastic shroud having a first bore portion, said first portion having the assembled electrode disc core and liner received and sealed therein, the PCTFE plastic shroud having a second bore portion receiving at least part of an electrode contact, and a spring extending in the second bore portion between the electrode contact and the electrode disc core to complete the conductive path from the disc selectively submerged in the fluid .
An electrode for electrolytic fluid testing comprising an electrode disc core, an electrode contact, a spring electrically connecting the electrode disc core to the electrode contact, a PTFE flurocarbon plastic shroud encasing the electrode disc core, spring and at least part of the electrode contact and a TFE fluorocarbon plastic liner sealing the disc core to the shroud.
