Vaccine storage temperatures must be monitored with a calibrated digital thermometer/data logger with a biosafe glycol-encased probe (or a similar temperature buffered probe). Dial thermometers and digital devices without a certificate of calibration are not acceptable.

All VFC and VFAAR sites will be issued 2 LogTag digital data logger recorder units. All digital devices must have a certificate of calibration from an accredited laboratory (see Checklist for Thermometer Certificate of Traceability and Calibration form).
