COMPOSITE CHANNEL JUNCTION

摘要

An electrochemical sensor structure (30) includes a housing (32) having an inner surface defining a housing cavity (42). The sensor (30) also has an inner body (34) having an outer surface (51). The outer surface (51) of the inner body (34) and the inner surface of the housing (32) have engaging portions which directly engage one another to for m a channel therebetween. The channel defines an ionic junction in the sensor (30).
