FlashLink In-Transit USB Data LoggerDeltaTrak’s FlashLink® USB In-Transit Data Loggers are ideal management tools for monitoring temperature sensitive and perishable commodities as they travel through the cold chain, from produce and prepared foods, to chemicals and pharmaceuticals. This single-use data logger is equipped with a USB connection to easily upload data to the PC and provides temperature history information ranging from -40°C (-40°F) up to 65°C (150°F). The data logger can be purchased in 5, 15, 45, and 75 day temperature data logging periods and its patented Shadow Log feature guarantees that trip temperature is available even if the operator fails to start the temperature data logger. The unit can also be custom programmed at the factory with up to 6 multiple alarm zone time limits. Each zone can be programmed for a set time limit and the data logger will track cumulative time the temperature was within that range.
