Definition & Explanation

Maintaining cold chain integrity depends on complete, uninterrupted temperature records throughout the supply chain – which is exactly what data logging for cold chain monitoring delivers. Electronic data loggers are activated when loading reefer containers, refrigerated trucks, or air cargo units, recording temperature, humidity, and sometimes pressure at configurable intervals. On delivery, the stored readings are downloaded and checked to confirm that cargo remained within the agreed temperature bands at all times. For pharmaceuticals, fresh produce, and biologics, this record is both a regulatory requirement and the evidentiary basis for any cargo insurance claim. A recorded temperature excursion immediately triggers quality investigations or product rejection procedures.
