How are thermometers calibrated
WebTHERMOMETERS Purpose This instruction defines how to calibrate thermometers to be used by USDA graders. Policy Graders and Supervisors will ensure all thermometers are calibrated prior to production. Accuracy is critical when certifying temperature for contract acceptance and commodity specifications. 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.
