FlashLink® PDF In-Transit Data Logger, Model 40420-40451

This single-use in-transit temperature logger is an ideal cold chain management solution for monitoring temperature sensitive products as they are transported through the supply chain. A built-in USB connector and on-board software make it convenient for global distribution, since special reading devices are not required and there is no need to purchase software for downloading trip data. It is particularly important to have these features when loggers accompany products to remote locations; it means that receivers will have quick and easy access to temperature reports as soon as a shipment arrives.
