Anonymised Temperature Mapping Europe examples. No client names, but concrete situations, duration, loggers, risk and conclusion.
Situation: medicine fridge with multiple shelves and door load. Duration: 48 hours. Loggers: 9. Risk found: coldest zone at rear wall, warmest zone near door shelf. Conclusion: do not place routine sensor in door zone; define alarm limits and shelf use.
Situation: API storage in a warehouse with a dispatch door. Duration: 7 days. Loggers: 15. Risk found: warm zone near dispatch and external wall. Conclusion: move monitoring position to critical product zone and document a controlled door-use procedure.
Situation: ULT freezer with racks and frequent door openings. Duration: 72 hours. Loggers: 12. Risk found: slower recovery at top after opening. Conclusion: limit loading and door openings; link monitoring position to warmest representative zone.
Situation: refrigerated storage with evaporator and product racks. Duration: 5 days. Loggers: 18. Risk found: cold spot under air outlet and warmer zone near the door. Conclusion: avoid storing products directly under the air outlet; place routine sensor at critical product position.
QA-led temperature mapping: from self-measurement with calibrated loggers to an audit-ready dossier, without unnecessary complexity.
