LogTag UTREL-16F

Multi-use low temperature Logger with USB and external probe

Multi-use low temperature Logger with USB and external probe


  • Read current temperature and alarm condition at a glance.
  • Display showing temperature and alarm status of up to six alarms.
  • Automatic generation of a PDF report  as a permanent record of the data.
  • Fixed battery of 1 year storage, 2 years of normal use.
  • Up to 16.000 recordings - enough for 168 days at 15 minute logging

The display shows recording status, current temperature, alarm status of up to six user-configurable alarms and duration of any temperature excursions.

When the UTREL-16F is connected to a computer using the integrated USB plug, a detailed PDF report of the recorded temperature data and alarms can be automatically generated without the need for extra accessories and proprietary software. For more detailed data analysis, the UTREL-16F also creates an encrypted data file compatible with LogTag Analyzer® operating software and data management options.

Automatic PDF Report

The UTREL-16F connects to a computer USB port for easy configuration by the user for a wide range of recording and alert conditions. Upon download, it automatically generates a fully detailed PDF report with the option to download the data using the freely available LogTag®Analyzer software for a more detailed analysis.
