Instructions: Foodservice employees will record the calibration temperature and corrective action taken, if applicable, on the Thermometer Calibration Log each time a thermometer is calibrated.
What is thermometer calibration?
Thermometers are one of the most important tools in your food business's toolbox and require proper calibration to verify the accuracy of the reading. Thermometer calibration means checking that your thermometer is working correctly, and making adjustments if it is not.Mar 28, 2019
How do you fill a calibration log thermometer?
Fill a Container with ice (crushed ice works best) and add water. There should be more ice than water. 2. Place the thermometer in the water so it is submerged past the indication on the stem (the indent).
What do you mean by calibration?
Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. ... Calibrations are performed using only a few calibrators to establish the correlation at specific points within the instrument's operating range.

How do you calibrate a probe?
- Step 1: Boil tap water and pour into a suitable container (such a mug or beaker)
- Step 2: Place your thermometer into the container.
- Step 3: Wait for 2 minutes.
- Step 4: Check that the temperature is between 99°C and 101°C (210°F to 214°F)
What are the steps to calibrate a thermometer?
- HOW TO CALIBRATE. A THERMOMETER.
- Fill a large container with crushed ice. Add clean tap water until the container is full. Stir the mixture well. ...
- Thermometers should be calibrated regularly to make sure the readings are correct. The ice-point method is the most widely used method to calibrate a thermometer.
What is the most accurate method for calibrating thermometers?
To calibrate a thermometer, you must first test its accuracy in a substance with a known temperature. Then you'll adjust the thermometer to match that temperature. There are two common methods for thermometer calibration in food service: the boiling point method and the freezing point method.
How do you calibrate a thermometer in chemistry?
- Fill a glass with ice cubes, then top off with cold water.
- Stir the water and let sit for 3 minutes.
- Stir again, then insert your thermometer into the glass, making sure not to touch the sides.
- The temperature should read 32°F (0°C). Record the difference and offset your thermometer as appropriate.
How do you tell if a thermometer has been calibrated?
- Fill a tall glass with ice and add cold water.
- Place and hold the thermometer in the ice water for 30 seconds without touching the sides or bottom of the glass. ...
- If the thermometer reads 32°F, it is reading correctly and can be used.
