Do you use ice and boiling water to calibrate temperature? There's a better way.

Using ice and boiling water to calibrate temperature is easy and fast. However, the water method can be inaccurate because of variations in altitude, atmospheric pressure and water purity -- and the inaccuracies are unknown. When you're calibrating you want to avoid as many unknowns and inaccuracies as possible.

Using a dry-block calibrator is a far better way to calibrate temperature. A dry-block provides a better measurement because it has a known accuracy.

In this brief video I will calibrate a digital thermometer with ice water and boiling water. Next I'll do the same calibration using Fluke Calibration 9100S and 9102S Handheld Dry-Wells.

Then we'll see how the two methods measure up against each other.
