Seeing what can't be seen in a triple point of argon system
The triple point of argon (83.8058 K ) is one of the most commonly used fixed points for the calibration of standard platinum resistance thermometers (SPRTs) at temperatures below 273.16 K. It’s a defining fixed point of the International Temperature Scale of 1990 (ITS-90). Fluke Calibration recently designed a new Triple Point of argon system with the goal in mind of achieving both efficiency and accuracy in calibrating SPRTs.
