How to Calibrate a Thermometer

Thermometers should be calibrated regulary to make sure the reading are correct. Here are the steps:

1. Fill a large container with ice. Add clean tap water until the container is full. Stir the mixture well.

2. Put th thermometer stem or probe into the ice water. Make sure the sensing are is under the water and not touching the sides of the container. Wait 30 seconds or until the reading stays steady.

3. Adjust the thermometer so it reads 32 °F (0 °C). Hold the calibration nut securely with a wrench or other tool and rotate the head of the thermometer until it reads 32 °F (0 °C).

4. Keep an accurate log of all calibrations done for each thermometer in your business. Please see an example of a calibration log below.
