Introduction

The research scope mainly focuses on temperature/humidity and thermophysical properties metrology:

  1. In the field of temperature measurement, in order to realize and disseminate the international temperature scale of 1990 (ITS-90), Center for Measurement Standards has the platinum resistance thermometer calibration technology, the noble metal thermocouple thermometer calibration technology, and the radiation thermometer calibration technology. In the field of new temperature standards, thermodynamic thermometer technology has been established, such as acoustic gas thermometer and absolute radiation thermometer system to measure the true thermodynamic temperature to get rid of the influence of the fixed points, and also prepare for the revise of the difference between ITS-90 and thermodynamic temperature. At the same time, in the aspect of high temperature calibration, metal-carbon alloy is used to replace the role of pure metal to reach the high temperature standard point above copper fixed point (1084.62 ˚C), and various metal-carbon eutectic points are successfully used to establish temperature standards from 1324 ˚C to 2748 ˚C. There are 4 different high temperature eutectic fixed points in this range.
  2. In the aspect of humidity standards, the dual pressure humidity generator humidity standard measurement system has been established.

In the field of thermophysical properties measurement, thermal conductivity, thermal diffusivity, emissivity, Seebeck coefficient and resistance measurement technology are established for renewable energy and energy-saving materials to be applied in microelectronics, green energy buildings, and aerospace, such as thermal grease, thermal barriers, insulation and coatings, and aerospace composites.
