FlashLink® USB PDF In-Transit Logger, Model 40543-40551

This single-use temperature logger is an ideal cold chain management solution for monitoring perishable 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 or install software for downloading trip data. These features are particularly beneficial when loggers accompany products to remote locations, because receivers will have quick and easy access to PDF reports with temperature history and can make accept/reject decisions as soon as a shipment arrives. Saved reports are easily emailed and archived for quality assurance, traceability, and regulatory compliance.
