Temperature Monitoring Devices

The Haier HETL-01, with internal sensor, is an electronic 30-Day Temperature Recorder (30DTR), with factory-programmed alarms and visual display for monitoring storage conditions in vaccine refrigerators (+2°C to +8°C) over a 30-day period. The device shows the actual temperature, all alarm violations over the previous 30 days (on a rolling basis), the daily minimum and maximum temperature of the last 30 days, and the time duration of any violation.

The Sensitech FreezeAlert is an electronic Irreversible Freeze Indicator (IFI) with an internal sensor, factory-programmed alarm, and visual display for indicating a freeze event during transport or storage of freeze-sensitive vaccines. The device indicates via a visual alarm when an exposure to temperatures below -0.5°C for longer than 60 minutes has occurred. The device needs to be activated prior to use and once an alarm has been triggered, cannot be re-used.
