Many Fluke Calibration pressure measuring instruments require periodic zeroing of the reference pressure transducer to correct for drift that occurs naturally over time. For the transducers that are intrinsically absolute, the zeroing process is often performed by comparison to local barometric pressure. This is a relatively simple task for laboratories that have access to a precision in-house barometer. With the exception of a few low pressure ranges, zero by comparison to an in...

I’m a big fan of calibration baths. When I managed our temperature calibration laboratory, I relied on them. With a series of baths and a liquid nitrogen comparator, we were able to perform a large volume of accredited temperature calibrations with lower uncertainties from -197 °C to 500 °C than would have been possible in any other way. Sometimes we would get a probe that was large and bent, or very small, or had a large handle and it would slow us down, but it would not stop us, because the...

Dave buys a new calibration bath because of a requirement to calibrate to –80°C. His boss notices the temperature range on the bath is from –80 °C to 110 °C. Sensing a new source of revenue, the boss says, “Great, now we can finally calibrate thermometers to 110 °C too.”
“No”, Dave says, “we can’t set the temperature higher than 70°C”
“Why, what’s wrong with the bath?”
“Nothing, it’s working perfectly.”
Confused and agitated, the boss leaves while mumbling something about temperature...
