Applications and Experiments for the Freeze Alert Indicator
The indicator travels or sits with freeze-sensitive vaccines and shows a cross if they may have been exposed to freezing, so staff know to check the stock before use. Because it can wait 12 months inactive and then runs for 36 months, it suits planned roll-outs and freeze-monitoring practicals in nursing and pharmacy training.
- Monitoring the cabinet of a small solar refrigerator such as the 27 L Solar Direct Drive Refrigerator Zero.
- Accompanying vaccines in transit in a long-range carrier such as the 1.6 L Freeze Free Vaccine Carrier.
- Checking cold boxes after delivery runs and recording any cross shown on the display.
- Demonstrating freeze-exposure checks to ANM, nursing and pharmacy trainees.
The coin cell is not replaceable; at the end of its life, dispose of the indicator as battery-containing electronic waste.
