This paper investigates the potential for using the freezing-points of high-purity metals for direct temperature calibration, on site and at low cost. These freezing-points are primary calibration points in the International Temperature Scale (ITS-90). It has been found that small amounts of high-purity metals can be obtained in the marketplace cheaply.(More)
An innovative process is proposed for the calibration of thermometric devices, combining materials which change state at primary temperature calibration points defined in international standards, and electrical impedance measurement techniques. The process will use pure samples of such materials and a measurement apparatus which enables the automated(More)
