Abstract

In this paper, we report on the development at NRC of a sulfur hexafluoride (\(\text {SF}_6\)) fixed-point cell for calibrating long-stem standard platinum resistance thermometers. Discussed in detail are the unique challenges of constructing the high-pressure fixed-point cell and realizing the triple point of \(\text {SF}_6\) in a commercial stirred liquid bath.

Keywords
