It'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.
