<P>PROBLEM TO BE SOLVED: To provide an oxygen concentration measuring apparatus in a metal fluid which is made of a solid electrolyte strong against a mechanical impact or a thermal impact, in which its mounting or replacing is simple and which has excellent maintainability and good sealability of the metal fluid. <P>SOLUTION: The oxygen concentration measuring apparatus comprises a measuring chamber 13 formed by connecting to a partition wall 12 of a part in which the metal fluid a exists, a circular or an elliptical circular shaped sold electrolyte 14 provided to closely partition the part of the side in which the fluid (a) exists and a reference gas space 19 side in which a reference gas is introduced, a piping system for introducing the reference gas to the space 19 of the chamber 13, and a voltmeter 28 for measuring an electromotive force generated between a reference electrode 22 formed by opposing to the space 19 side of the electrolyte 14 and the fluid (a) side. <P>COPYRIGHT: (C)2003,JPO |
