Conductance probe for detection of immiscible liquids

摘要

This application teaches a probe for detecting immiscible components in an aqueous system, particularly pollutants that contaminate ponds, rivers and aquifers. The probe includes a casing having an open bottom and electrical terminals adjacent the open bottom. Means are provided remote from said casing for detecting change in electrical characteristics, and connecting said remote means to said electrical terminals. The probe registers electrical characteristics on said remote means when said casing is immersed in water, and a variation in said characteristics when said casing passes through a dissimilar fluid.
