Realization of a New Definition of Kelvin on State Primary Standard of Temperature Unit Get 35-2021 in the Temperature Range from 0.3 To 273.16 K

  • Published:
Measurement Techniques Aims and scope

The article describes the composition and metrological characteristics of the State Primary Standard of temperature unit – kelvin – in the range from 0.3 K to 273.16 K GET 35-2021. GET 35-2021 allows reproducing and disseminating the temperature unit in accordance with the definition of kelvin, accepted at the 26th General Conference on Weights and Measures (26th CGPM) in 2018. GET 35-2021 includes three installations of acoustic gas thermometry developed in 2012–2019, which are the primary means of measuring temperature in the ranges of 79–273.16 K, 4.2–80K, 268.16–273.16 K. Equipment for reproducing the reference points of the International Temperature Scale ITS-90 has been upgraded in order to improve the accuracy. Based on the studies performed, the uncertainty of reproducing the thermodynamic temperature and temperature according to ITS-90 has been calculated.
