Reefer Container Temperature Recording Accuracy: Factors to Consider

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

Furthermore, it is worth noting 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 disparity 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 typical refrigerated reefer container can maintain its frozen state, even when the container's refrigeration system is not operational.
