The LogTag® TRIL-16U is an advanced ultra-low-temperature data logger, designed for highly accurate monitoring in extremely cold environments such as dry-ice transport, vaccine distribution and life-science applications. Thanks to the built-in USB connector, PDF and CSV reports can be downloaded instantly — entirely without software, cables or an interface cradle.
Equipped with LED indicators for immediate 'at-a-glance' status checking, the device immediately alerts on temperature deviations, allowing quick intervention. With more than 16,000 data points, this logger offers up to 66 days of reliable logging. For advanced configuration, the TRIL/SRIL-16U works seamlessly with LogTag® Analyzer and data can be automatically uploaded to LogTag® Online for secure cloud storage and remote access.
The robust, compact polycarbonate housing and outstanding performance down to -85°C make this data logger ideal for demanding cold-chain applications, both during transport and long-term storage.
