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.
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.
