Vaisala CCL100 loggers record and monitor time and temperature for vaccines, pharmaceuticals, biologics, and other perishable products during distribution and short-term storage. About the size of a credit card, the loggers are flat and feature an integrated USB connector that can be plugged directly into the USB port of a computer. Once connected, the logger automatically generates a PDF containing complete time and temperature history, including graphs and summary data. Each PDF report contains a secure, embedded .CSV file that can export to Microsoft Excel. Vaisala CCL100 loggers eliminate the need for proprietary readers and software, and are optimal in situations that require fully independent operation, including: clinical trials, materials transport, sample shipping, and "last mile" distribution.
