FlashLink® VU Produce In-Transit Logger, Model 20879-20889

This single-use in-transit data logger is accepted by most receivers and is the ideal cold chain management tool for tracking temperature during transportation of produce products. It can be used on all outbound loads, so suppliers are able to consolidate their temperature recorders to one model. Using the FlashLink VU Produce In-Transit Logger means there is no need to stock various brands in the shipping office, making inventory management easy, and eliminating the problem of running out of any one particular type of logger for a specific receiver.
