Using the Milk Thermometer Calibration Tool
HOW TO USE THE CALIBRATION TOOL
To calibrate your thermometer, you must use boiling (212°F/100°C) water.
To adjust to boiling water:
Use a boiling pan of water - remember that the water from your espresso machine is not supposed to be boiling, so donít use it as a guide.
After you have prepared the water, thread the thermometer stem through the hole in the calibration tool. Ensure that the nut on the underside of the thermometer face is aligned with the grooves in the calibration tool. Insert the thermometer into the boiling or freezing water. Turn the nut on the underside of the thermometer face with the calibration tool. This will move the pointer. Align the pointer to 212°F/100°C.
Your altitude will determine your actual reading - these are for readings taken at sea level. For above sea level readings - adjust your temperature using the following chart.
Elevation / Boiling Point
Sea Level / 212°F
2,000 ft. / 208°F
5,000 ft. / 203°F
7,500 ft. / 198°F
10,000 ft. / 194°F
