Abstract
The present invention is a device for measuring the temperature of a molten metal. The device includes a thermocouple element, a housing consisting of a heat-resistant material and a retainer member for receiving the thermocouple element. The retainer member has an open end and a closed end. The thermocouple element has a hot junction located proximate the closed end of the retainer member. The retainer member is positioned within the housing and is smaller in size than the housing to define a cavity therebetween. The cavity is substantially filled by a protective material which includes a metal oxide component and an oxygen reducing component.
