Libero Te1-P PDF Temperature Cryo-logger


When the requirement is to monitor cryogenic temperatures or to ship products in Cryoshippers, the Libero Te1-P is the ideal choice. The Logger can be mounted on the outside with only the probe being inserted into the tank. The display on the logger provides the current temperature, status (tick mark vs. cross), statistics, battery life, etc.

No external software is required to download data from the logger. All one has to do is detach the probe from the USB connector and plug it into the USB port of a computer. A PDF report is automatically generated. This report can be customized to include user-specified details.

The logger provides the ability to configure 5 alarm zones and can store 16,000 data points. The battery in the logger has been rated to last up to 3 years assuming 15 minute sampling interval.

  • External temperature sensor with rating of -200°C to +200°C. Ideal for Cryo shipper monitoring, ultra-low freezer, etc.
  • Creates automatically a PDF report when connected to USB port of a PC
  • Can store up to 16000 temperature data points
  • A multi-function display shows pass/fail status, battery life, statistics, etc
  • Validation certificate stored in the data logger
  • 5 temperature alarm levels with single or cumulative delays
