- STEP 3: INSERT THE THERMOMETER. …
- STEP 4: CHECK THE TEMPERATURE. …
- STEP 5: RECORD THE TEMPERATURE.
How do I know if my thermometer needs to be calibrated?
If a thermometer is ever dropped, you should go ahead and calibrate it. If a thermometer is going from a wide variety of temperatures (from freezing temperatures to boiling temperatures), it should also be calibrated more frequently. Every time you invest in a new thermometer, calibrate it before using it.
How is a glass thermometer calibrated?
The calibration process for glass thermometers involves the direct comparison of the thermometer reading with a highly accurate temperature reference standard, such as a Platinum Resistance Thermometer (PRT).
What is the most common method used to calibrate bimetallic stemmed thermometers?
Bimetallic stemmed thermometers are calibrated using the ice-point method. Calibrate on a regular basis and after using the thermometer with very hot or very cold foods, or after dropping or jarring it.
