We use some thermohygrometers to monitor environmental conditions in a controlled environment (medical device manufacturing). We appear to have established some somewhat arbitrary limits a number of years ago. I've never been worried about reaching a limit without someone complaining well beforehand.
When it comes to calibrating equipment of this type and purpose it seems many manufacturers do a single point or two point calibration. I think this is reasonable because the range of operation is very small (50 to 85°F) but our quality engineers insist we should be using a 3 point calibration. The cost to do this exceeds the value of the equipment so we are in the position of replacing the equipment instead of calibrating it.
I am curious what other people in the industry are doing.
thanks
