Temperature calibration involves the process of verifying and adjusting the accuracy of temperature measurement devices to ensure they provide correct readings. In cold chain operations, this process is vital for equipment such as refrigerated storage units, transport vehicles, and temperature data loggers. Accurate temperature readings are essential to maintain the required environmental conditions for perishable goods. According to the "Calibration Specification for Temperature Parameters of Refrigerated and Frozen Transport Vehicles and Containers," proper calibration methods provide a unified and scientifically sound technical basis for assessing the temperature performance of cold chain logistics equipment. Regular calibration ensures that temperature-sensitive products remain within specified ranges, preserving their quality and extending shelf life.
