Abstract:
1. A conductivity sensor comprising: a) a sensor body having an inner surface and an outer surface; b) a first electrode that is formed of a solid conducting material comprising at least one of solid 10 carrot gold, solid 14 carrot gold, and solid 18 carrot gold that is positioned through the inner surface of sensor body; c) a second electrode that is formed of a solid conducting material comprising at least one of solid 10 carrot gold, solid 14 carrot gold, and solid 18 carrot gold that is positioned through the inner surface of sensor body and adjacent to the first electrode; and d) an epoxy resin deposited in the inner surface of the sensor body so as to encapsulate a portion of the first electrode and a portion of the second electrode, the epoxy resin forming an active surface that exposes a first end of the first electrode and a first end the second electrode for conductivity measurement and forming a connector surface that exposes a second end of the first electrode and a second end of the second electrode for electrically interfacing with a conductivity measurement circuit.
