Construction of the acoustic gas thermometer in the range from 79 to 273,16 К
The installation of relative acoustic gas thermometry, developed at the FSUE "VNIIFTRI", is described. The installation, which is designed to reproduce and transmit the units of temperature in accordance with the new definition ofkelvin in the temperature range from 79 to 273.16 K, became the part of the State primary standard for the unit of temperature - kelvin in the range from 0.3 to 273.16 K.
