Why is calibration of monitoring devices important?

• A. To ensure accuracy of measurements used to determine whether critical limits are met; prevent false deviations.
• B. To speed up production
• C. To reduce energy consumption
• D. To simplify data recording

Answer: (A)

Calibration keeps monitoring readings trustworthy. In HACCP, monitoring devices tell you whether a CCP is within its critical limit, so the data must reflect true values. If a thermometer, pH meter, or timer drifts, you could misread the process state—believing everything is within limits when it isn’t, or triggering actions when there’s no real issue. Regular calibration against known standards reduces measurement bias and uncertainty, so decisions about critical limits are based on accurate data. It also provides traceability and records of instrument performance, supporting timely corrective actions and product safety. The other options don’t fit because calibration doesn’t directly speed production, reduce energy use, or simplify data recording; its primary effect is ensuring measurement accuracy and reliable decision-making.
