Hongke’s ELPRO LIBERO C Series is the world’s first brand to introduce temperature data loggers that generate reports in PDF format. These reports are fully compliant with the PDF/A standard (ISO 19005-1), providing comprehensive support to help users meet stringent global regulatory requirements such as GMP, GLP, and FDA 21 CFR Part 11.

Hongke LIBERO Series Temperature Loggers

To address the cold chain compliance needs of Chinese pharmaceutical companies expanding into overseas markets, the LIBERO series offers the following key solutions:

• Air Transport Compliance: Verifiable with Documentation: The Hongke LIBERO series has received dual certification—the “Certificate of Compliance with Conditions of Carriage” from the Shanghai Research Institute of Chemical Industry and the “Air Transport Conditions Assessment Report” from Beijing DGM—and fully complies with the exceptions for functional equipment outlined in the International Air Transport Association (IATA) Dangerous Goods Regulations. Currently, more than 40 major airlines worldwide have included it on their approved lists. This means that the temperature monitoring equipment itself will not pose an obstacle during air cargo security screening, and pharmaceutical companies and freight forwarders do not need to prepare additional dangerous goods declaration documents for this purpose.

• Plug-and-play, no additional training required: The Hongke LIBERO series is the first-of-its-kind PDF temperature logger; the PDF reports it generates can be automatically converted into tamper-proof PDF temperature data reports simply by plugging the device into any computer’s USB port. Recipients anywhere in the world do not need to install specific software, purchase a card reader, or undergo operational training. For scenarios involving multiple receiving locations—such as international multicenter clinical trials (MRCTs) and drug exports—this “zero-barrier” design significantly reduces the probability of human error at the operational level.

• Compliant Data, Globally Recognized: The PDF reports generated by the Hongke LIBERO series are non-editable, fully meeting the FDA’s requirements for electronic records while helping users comply with major pharmaceutical supply chain regulations such as GSP, GMP, GDP, and WHO standards. From Pfizer to Novo Nordisk, and from GSK to Bayer, many of the world’s top 50 pharmaceutical companies are long-standing customers of ELPRO—a fact that serves as the most direct and compelling validation of its compliance capabilities.

• Single-use, extremely cost-effective (great value for the price): In export shipping scenarios, temperature loggers typically do not need to be returned, so a single-use solution is the most efficient option. Hongke’s ELPRO LIBERO CB eliminates the need for return management processes and cross-border logistics costs, resulting in a significantly lower cost per use compared to solutions that require multiple returns. A single model supports multiple temperature configurations, reducing the number of SKUs in inventory and further alleviating procurement and warehousing pressures.
