Facilities Were Established for Boltzmann Constant and Thermodynamic Temperature Measurement


The Contact Thermometry Laboratory, a  branch lab of Division of Thermophysics and Process Measurements, studies the key measuring technologies of Boltzmann constant and thermodynamic temperature. It  then establishes a measuring device to redetermine Boltzmann constant by the fixed-path-length cylindrical resonators.

It plays an important role in re-defining of fundamental SI units on the fundamental natural constants and is a good attempt to keep up with the development pace of international temperature metrology.
