摘要：<P>PROBLEM TO BE SOLVED: To provide an oxygen sensor for accurately measuring the concentration of dissolved oxygen by preventing the oxidation of a lead wire on the standard side. <P>SOLUTION: The oxygen sensor S is constituted so that a container-shaped measuring part 27, which comprises a solid electrolyte and comes into contact with a liquid metal, is connected to the leading end of a conductive hollow tubular extension sleeve 25, and a standard electrode 33 is housed in the container-shaped measuring part 27, while a lead wire 30 for a standard electrode 33 is inserted in the standard electrode 33 to measure the voltage applied across the standard electrode 33 and the extension sleeve 25. This oxygen sensor S is filled with an oxidation preventing gas (g). <P>COPYRIGHT: (C)2006,JPO&NCIPI
