Data Logger and Temperature Monitoring

Digital Data Logger (DDL)

Every TempArmour® Vaccine Refrigerator and TempArmour® Vaccine Freezer includes a high quality certified and calibrated digital data logger (DDL)  as we believe it is important that all our customers have the very best equipment possible to effectively manage their vaccines.

The specifications of the data logger options meet CDC and VFC* requirements and are outlined below.
*Attention VFC Providers: Although the vast majority of VFC Programs accept this data logger, check with your VFC Program as some may have preferences for Models that best integrate with their system.
