The Euramet Metrology Research Programme Project Implementing the New Kelvin (InK)

The kelvin, along with the ampere, kilogram, and the mole are likely to be redefined in terms of fundamental constants, in line with Conférence Générale des Poids et Mesures resolution 1 (2011), sometime before 2020. In advance of, and to support, the redefinition, a mise en pratique of the definition of the kelvin (MeP-K) is currently being prepared. The Euramet Metrology Research Programme Implementing the newkelvin (InK) project will coordinate research activity in this field with the objective of improving primary thermometry over the range from 0.0009K to >3000K. Specifically, the project will aim to pursue the following three broad objectives: (1) Support the development of primary thermometry techniques for the realization and dissemination of thermodynamic temperatures, particularly at high (>1300K) and low (
