Libero Ti1-L USB PDF Temperature Logger (3 year life)


Tamperproof Libero Ti1-L data logger combines a device life of 3 years with the ability to directly generate a PDF report, when connected to the USB port of any PC. The Libero is the first PDF data logger in the world which complies with ISO 19005-1, thereby ensuring the long-term preservation capability of the report generated. It also meets 21CFR Part 11 requirements.

The sender presses the TRANSIT button on the logger before despatch. On receipt, the goods receiver presses the ARRIVED button and then download the PDF report. What is viewed at the receiver end is a report that can be configured and can be limited to a simple pass or fail mark. The PDF report file also contains raw data, that can be analysed in detail using elproVIEWER software. This software is available free of cost.
