- Аннотация: The article describes the composition and metrological characteristics of the State Primary Standard oftemperature unit – kelvin – in the range from 0.3 K to 273.16 K GET 35-2021. GET 35-2021 allows reproducingand disseminating the temperature unit in accordance with the defi nition of kelvin, accepted at the26th General Conference on Weights and Measures (26th CGPM) in 2018. GET 35-2021 includes threeinstallations of acoustic gas thermometry developed in 2012–2019, which are the primary means of measuringtemperature in the ranges of 79–273.16 K, 4.2–80K, 268.16–273.16 K. Equipment for reproducingthe reference points of the International Temperature Scale ITS-90 has been upgraded in order to improvethe accuracy. Based on the studies performed, the uncertainty of reproducing the thermodynamic temperatureand temperature according to ITS-90 has been calculated.
