Abstract

The measurement of temperatures above 1100 °C is undergoing a step change improvement with the development of high temperature fixed-points and improved thermocouple types such as Pt/Pd. This paper reviews international developments in these areas that could lead to an improved way of realising ITS-90 above the Ag point, reduced thermocouple uncertainties by factors of two or more, and improved dissemination and measurement of high temperatures to industry.
