How to Calibrate a Meat Thermometer

The usual hard knocks of kitchen work can make an analog instant-read thermometer inaccurate over time. Make sure your trusty thermometer is showing you the right temperature.

Things You'll Need

  • Ice
  • Short Glass
  • Small Pot
  • Needle-nose Pliers

Instructions

  1. Bring a small pot of water to a boil.

  2. Fill a short glass with water and plenty of ice.

  3. Remove the thermometer from its plastic guard and place it in the boiling water.

  4. If it doesn't read 212°F (100°C), turn the nut behind the face with needle-nose pliers. Only tiny adjustments are required; recheck as needed.

  5. Place the thermometer in the ice water.

  6. If it doesn't read 32°F (0°C), adjust the nut. Once it is properly calibrated, the thermometer will read the correct temperatures of both boiling and iced water.
