Abstract:
1. A self-condensing sensor assembly for monitoring pH: An outer tubular member; an inner tubular member, said outer tubular member co-linearly enclosing an inner tubular member; an antimony sensor enclosed within said inner tubular member; a reference element enclosed within said outer tubular member and located in a proximal position to said antimony sensor; a wick material, said wick material having one side which partially surrounds and substantially engages a portion of said inner tubular member, said wick material extending from said antimony sensor to a proximal position whereby said wick material is substantially engaged to said reference element; an ion conduction fluid entrained or retained within said wick material; and said self-condensing sensor having the capability to establish an electrical connection via micro-droplets condensed across said antimony sensor and said reference element.
