Thermis Log 1 Single-use Temperature Logger
Thermis Log 1 is a compact, single-use USB temperature recorder for reliable cold-chain monitoring. It combines high measurement accuracy, long-duration recording and automatic report generation for transport, storage and quality-control applications.
Introduction
Thermis Log 1 is a factory-prepared, single-use USB temperature recorder developed for monitoring temperature-sensitive goods throughout transportation and storage. Its slim card-style design makes it easy to place inside cartons, insulated boxes, refrigerated vehicles, medical coolers and laboratory shipments without taking up valuable packing space.
Once activated, the logger measures and stores temperature at the configured interval for the selected trip duration. The integrated USB connector allows the receiving team to connect the device directly to a Windows or Mac computer and generate a secure PDF, CSV or combined report without a separate reader or specialised download equipment.
With temperature accuracy of up to ±0.3°C, a three-year shelf life, capacity for as many as 129,600 readings and recording programmes available for journeys of up to 180 days, Thermis Log 1 supports detailed cold-chain verification. It is suitable for pharmaceutical distribution, vaccines, biological materials, clinical samples, food, fresh produce and other products requiring documented temperature control.
