Российские ученые создали новый мировой эталон температуры

Russian scientists have created a new world standard in temperature, which would give Russia one of the leading places in the world in this line of research, told RIA Novosti in Rosstandart.

“The Russian researchers, metrologists were able to determine the Boltzmann constant with high accuracy, thereby improving the accuracy of the reproduction of the unit of temperature. The obtained results will be used to state the reference of the complex will give Russia one of the leading places in the world in the field of temperature measurement”, – stated in the message.

As explained in Rosstandart, scientists have developed the equipment gives the opportunity to improve the metrological characteristics of the state primary standard of unit of temperature, namely to extend the range of reproduction of the unit of temperature to 3473 K (Kelvin) and reduce reproduction error in 1.5 – 2 times.

“At the moment manufactured and passed all the necessary research and experimental equipment and measuring installations for the transition to a new definition of the unit of temperature”, – said the Rosstandart.

The study was conducted by the Russian research Institute of Metrology named after Mendeleev all-Russian scientific and research Institute of physical-technical and Radiotechnical measurements, within the structure of the Federal Agency for technical regulation and Metrology (Rosstandart).

The Boltzmann constant is a fundamental physical constant set experimentally determining the relationship of temperature and energy.
