What is necessary to ensure accurate temperature measurements in cooking?

Regular calibration of the thermometer is essential to ensure that it provides accurate temperature readings. Over time, thermometers can become less accurate due to various factors such as wear and tear or changes in temperature standards. Calibrating the thermometer ensures that it is measuring temperatures correctly, allowing for safe cooking practices, food safety, and adherence to health regulations.

While regular cleaning of the thermometer is important to maintain hygiene and prevent cross-contamination, it does not ensure measurement accuracy directly. Using multiple thermometers is not typically necessary and could lead to confusion if they display different readings. Storing thermometers at room temperature might not affect their accuracy directly, but appropriate storage should be combined with regular calibration to ensure reliable readings.
