A freaking *lot* if it's calibrated so it can for sure measure up to 
0,1C and not just show that way and the service contract includes yearly 
(oslt) re-calibrations.

Mission critical: you take 5 UPS's, 5 PC's, 5 sensors and wire them up 
separately. If all five from even the cheapest hardware break down 
simultaneously enough, you're having the worst luck of the world 
already. OTOH, then you won't have A) service contract, B) scheduled 
re-calibrations, C) calibration at the first place.

You weren't involved -> it's not your call -> you shouldn't stress about it.
