We have three mercury-in-glass thermometers. We calibrated them before first putting them into use. That was about one year ago. By the suggestion on the calibration certificate issued by an external lab, we should calibrate them once per year.
I’m not fully convinced that we should calibrate fluid-in-glass thermometer once per year. I prefer to calibrate them once for all. I want to see, how other factories schedule their liquid-in-glass thermometer calibration activities.
