  • Method and apparatus for measuring the oxygen potential of a heat-treatment furnance
    Patent number: 5352344
    Abstract: A probe for measuring oxygen potential, especially to determine the carboransfer properties of a furnace atmosphere containing the gases H.sub.2, CO, and CH.sub.4, with the probe having an oxygen ion conducting, solid measuring electrolyte with a contact electrode in the furnace atmosphere and a contact electrode in a reference medium that has a known oxygen concentration. To improve the accuracy of the measurement, an oxygen ion conductive compensation electrolyte in the form of a detachable solid body is connected between the contact electrode in the furnace atmosphere and the solid measuring electrolyte.
