Abstract
A conductivity sensor is provided having an elongated non-conductive body. First and second electrodes extend from the body and are vertically separated from each other. Preferably, the body has a slot therein running partially away from the bottom of the body and being open in a radially outwardly direction. An upper portion of the slot defines a downwardly facing ledge. The first electrode extends through an upper portion of the body and terminates at a lower edge of the body. The second electrode, shorter than the first electrode, extends through an upper portion of the body and terminates at the ledge.
