Sage Journals: Discover world-class research

Abstract

In my previous article [1] I discussed some of the innovations that are taking place at the National Physical Laboratory (NPL) in improving high temperature measurement. Starting with the current defined temperature scale ITS-90 [2, 3], I introduced the concepts of high-temperature fixed points [4], new types of thermocouple for use to 1500°C [5, 6] and developments in self-validation for contact thermometry sensors [7] and showed that high temperature measurement is undergoing a quiet revolution throughout the measurement chain. Here I want to set the work at NPL in a broader context of developments in the European Union (EU), again led from NPL, through the European Metrology Research Programme project “HiTeMS: High Temperature Measurement Solutions for Industry”.
