How are thermometers calibrated
Web2. Calibration is pretty easy: take an isothermal environment and measure two events with known physical effects: an ice-water bath and boiling point of water. Define your thermometer to read those well defined values at these well defined temperatures and, assuming your thermometer has a roughly linear scaling, you have just calibrated your ... WebInfrared thermometers can be calibrated for accuracy just like other thermometers. Technicians use industrial black bodies, however, you can do a quick calibration using a properly made ice bath.
