How to Calibrate a Probe Thermometer How to Calibrate a Probe Thermometer

What You'll Need
Water
Pot
Stove
Ice cubes
Thermometer
Jar, cup or bowl

With a probe thermometer it is important that the temperature be as accurate as possible in order to achieve the best results. Calibration every few months might be necessary to ensure accurate readings.

Step 1 -Ice

Fill a glass jar or cup to the brim with the ice. Add 1/2 cup of water and allow to sit for 3-5 minutes to adequately chill the water. Reset the thermometer and place it into the water. Make sure it is not resting on the glass. Wait two minutes for an accurate reading. The temperature should read 32 degrees Fahrenheit. If it does not, adjust the reading.

Step 2 - Boiling

Put a pot of water on the stove to boil. Wait till the water is boiling vigorously for at least 5 minutes. Remove from heat. Quickly reset the thermometer and place the probe into the water. Make sure it isn't resting on the pot. After 2 minutes, the probe should read 212 degrees Fahrenheit. If needed, recalibrate the probe to 212 degrees.

Step 3 - Storage

Overexposure to moisture and temperature fluctuations can cause thermometers to need recalibration. Store the thermometer in a clean, dry place where temperatures are constant.
