Refrigeration equipment is not always reliable. Multiple handlers may come in contact with the package during its journey. Unexpected delays and neglect at any stage of production or distribution can cause exposure to unacceptable temperatures. These types of risks may occur in storage before the product leaves a facility, in transit or after it arrives at its destination. By using temperature recorders the shipper will be enabled to monitor the complete coldchain to select if any part during transportation kept the handling instructions or not. This helps by detecting who caused any temperature damages.
