Make A House Call In Your Own House: Calibrating
Your Food Thermometer
Have you ever thought of taking your thermometer's temperature?
The American Dietetic Association recommend giving your
non-digital food thermometer a regular check-up.
There are two simple methods to check the accuracy of a food thermometer. However, not all thermometers can be calibrated - so make sure to check the manufacturer's instructions. Thermometers that can be calibrated usually contain a nut under the dial that can be adjusted with small pliers or a wrench.
Boiling Water Method
- Materials needed: one deep pot and water
In a deep pot, bring water to a rolling boil. Dip the thermometer stem two inches into the boiling water without touching the bottom. Wait for 30 seconds and the thermometer should read 212 degrees Fahrenheit. If it doesn't, adjust the temperature by turning the calibration nut underneath the head of the thermometer according to the manufacturer's directions.
Note:
In high-altitude areas, water boils
at a lower temperature, so check with your local Cooperative
Extension Service or Health Department for the exact temperature
of boiling water in your area.
