How often should most thermometers (excluding bimetallic) be calibrated?

• A. As often as needed according to the manufacturer's instructions
• B. Daily
• C. Weekly
• D. Never

Answer: (A)

Ensuring thermometer readings are accurate is crucial for safe cooking and holding temperatures. Because different thermometers use different sensing technologies and have different calibration needs, the best rule is to calibrate as often as needed according to the manufacturer’s instructions. Following the manual guarantees you’re using the correct method and interval for that specific device, keeping readings reliable even after drops, cleaning, or exposure to extreme temperatures. Other schedules like daily or weekly can be more rigid than necessary for some devices, and never calibrating is unsafe because readings can drift over time. If you ever doubt a reading, recalibrate per the manufacturer’s guidance.
