Vaccine Fridge Temperature Monitoring Dashboard

The default band is 2–8 °C, the universal cold-chain range for most refrigerated vaccines. Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

Don't discard on a glance — quarantine and check the manufacturer's stability data. Many vaccines tolerate brief excursions within defined limits, but several (e.g. adjuvanted and some mRNA products) are damaged by any freezing. Record the exact temperature and duration, label the stock 'do not use', and follow your immunisation programme's excursion protocol or call the manufacturer. A buffered probe and continuous logging are exactly what let you prove whether the product itself actually went out of range.

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
