Abstract
A procedure is proposed and experimentally verified for determining the metrological characteristics of temperature calibrators using the fixed point of indium solidification in a miniature ampoule with the aid of a multi-junction differential thermocouple. The procedure allows calibrator-reproducible temperature-value errors to be determined, along with calibrator nonuniformity and instability.
