Another NCSLI conference is in the books
Another NCSLI conference is in the books. This year, the metrology faithful (and budget funded!) once again gathered to gain knowledge through tutorials and technical presentations, contribute to the industry through attendance of committee meetings, talk to vendors at the exhibition, network with some of the world’s experts in metrology and spend time with old friends. There were so many great things happening that I didn’t even have time to compose a single tweet!

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.
