Reefer Container Temperature Accuracy: Factors Affecting Recorded Readings

Moreover, it's important to note that the temperature records provided were obtained from a temperature recorder placed inside the reefer container by the shipper. However, it's crucial to understand that these recorded temperatures may not accurately reflect the actual refrigeration temperature within the reefer container. Various factors such as the placement of the recorder, the condition of cargo stowage inside the container, and the accuracy of the recorder itself can all contribute to discrepancies in the recorded temperature.

Furthermore, it's worth mentioning that the temperature difference between the recorded temperature and the actual temperature of the cargo can be even more significant. This is primarily due to the substantial difference in specific heat capacity between the cargo and the air inside the container. Consequently, the temperature of the cargo does not change rapidly within a short period of time. In fact, frozen cargo in a standard refrigerated reefer container can maintain its frozen state, even when the reefer container is not actively refrigerated.
