Well said. The ability to better realize primary standards and disseminate that to secondary metrology labs from national standards is so critical.
It’s the same reason I think the work done in changing the SI definition to physical constants is so critical. In a decade or so all secondary labs should have capabilities to measure directly to the definition of a unit without needing to do comparison measurements to national standards. To me it seems like the metrology equivalent of “open sourcing SI units”
- m-ee 6y agoIt's important work and it can be surprisingly easy to run into the limits of your uncertainty. If you ask someone to measure a temperature in my experience 9/10 times they'll grab a type K thermocouple. Far fewer than 9/10 will tell you that the number they gave you is only guaranteed to be +/-3 degrees. That's good enough for a lot of applications but not all of them, and when something is really critical it helps to understand the full stack if your supplier/lab/coworker is making questionable claims about their accuracy.
