The Comparison Between the Freezing Point and Melting Point of Tin
Abstract: Preliminary data from thirteen Standard Platinum Resistance Thermometers (SPRTs) on eighteen pair of freezing and melting curves of high-purity tin (better than 99.9999%) showed that the average calibration difference between the melting point a

THE INTERNATIONAL TEMPERATURE SCALE OF 1990 (ITS-90)
Yes, there is an official temperature scale. It is based on the true, thermodynamic temperature scale, but the real, working temperature scale is something practical which can be repeatably produced anywhere in the world given the correct practices and eq

Why Use a Triple Point of Water?
Extract: If you use SPRTs, the Triple Point of Water Cell is your most important fixed-point because ITS-90 specifies the interpolation equations of an SPRT based on its resistance ratio stated as W(t)=R(t)/R(0.01°C), thus requiring you to measure the res
