How often must the hauler's thermometer be checked for accuracy?

The correct answer is that the hauler's thermometer must be checked for accuracy once every six months. This regular interval is essential to ensure that the thermometer maintains precision in measuring temperature, which is critical for maintaining product integrity and safety in any operations involving temperature-sensitive materials.

By checking the thermometer biannually, it helps to identify any drift in the accuracy of the device, allowing for timely calibration or replacement as necessary. Such diligence minimizes the risk of errors in temperature readings that could lead to spoilage, safety hazards, or compliance issues. Regular accuracy checks also align with best practices in quality control and regulatory requirements in various industries, ensuring consistent performance and reliability of the temperature measurement tool.
