REUSABLE MINIATURIZED REFERENCE ELECTRODE

摘要

A double junction reference electrode for use with chloride sensitive sensors comprising: an internal casing enclosing an inner chamber containing an internal electrolyte, with a top cap covering one end and a bottom cap covering the other end; a reference electrode protruding into inner chamber; an external casing disposed around the internal casing and enclosing an outer chamber between said internal casing and external casing, outer chamber containing an external electrolyte and a top plug covering one end and a bottom plug covering the other end; an internal junction bridge passing from the inner chamber through the bottom cap and into the outer chamber; an external junction bridge passing from the outer chamber through the bottom plug to protrude outside wherein the outer electrolyte is 5 times the concentration of the inner electrolyte such that there is no chloride ions leakage.
