How to Calibrate a Digital Thermometer with a Dry-Block Calibrator and with Freezing and Boiling Water

This video demonstrates two methods for calibrating a digital thermometer: first, with ice and boiling water, and second, with our Fluke dry-block calibrators. Both methods are easy and fast. However, the water method has inaccuracies that are unknown caused by variations in altitude, atmospheric pressure, and water purity. The dry-block calibration method provides a better measurement because we’re working with instruments that have a known accuracy.
