Clinical temperature monitoring
A freezer that failed on Saturday should not be discovered on Monday.
Continuous temperature monitoring for vaccine storage, blood and tissue banking, laboratory instruments and pharmaceutical storage — with the retained record an accreditation body expects to see.
The stock is worth more than the equipment holding it
A single compromised vaccine refrigerator can hold more value than the monitoring for an entire facility — and the loss is rarely just financial.
Not twice a day
Manual logs record two moments and infer the rest. Continuous monitoring records what actually happened overnight, at the weekend, and during the power cut nobody was there for.
Someone is told
An excursion raises an alert to a named person by a route they will actually notice, with escalation if it is not acknowledged. A log that records a failure nobody sees has not prevented anything.
Retained and exportable
Full interval history retained and exportable per unit and per date range, so a surveyor's question is answered from records rather than memory.
Storage ranges we monitor against
Alarm limits are configured per unit and per product. These are the commonly cited reference ranges.
| Storage | Typical range | Notes |
|---|---|---|
| Refrigerated vaccine | 2 °C – 8 °C | The range most routine vaccines are stored within |
| Frozen vaccine | −50 °C to −15 °C | Product-specific; check the manufacturer insert |
| Ultra-low freezer | −80 °C nominal | Specimen and reagent storage; probe choice matters |
| Whole blood / red cells | 1 °C – 6 °C | Tight window; in-unit core temperature preferred |
| Plasma, frozen | −18 °C or below | Longer-term frozen component storage |
| Controlled room temperature | 20 °C – 25 °C | Pharmaceutical storage, with excursion limits |
Ranges shown are widely published reference points, offered for orientation only. Always follow the manufacturer's storage instructions and your own accreditation requirements — those, not this table, are the authority.
Designed around what surveyors ask for
CDC Vaccines for Children
VFC storage and handling guidance expects continuous digital data logging with a certificate of calibration, a defined alarm response, and retained records available for review.
AABB and FDA expectations
Blood and tissue storage is expected to be continuously monitored with alarms set inside the acceptable range, tested periodically, and documented — including what was done when an alarm sounded.
CAP and CLIA accreditation
Accredited laboratories are expected to record temperatures for reagent refrigerators, freezers, incubators and water baths, and to document corrective action when a reading falls outside limits.
NIST-traceable, with certificates
Multi-point calibration traceable to NIST, with certificates retained — because the second question after "what did it read" is always "and why should we believe it".
