Logtag SRIL-8 Dry Ice Temperature Logger


Intended for use in transit monitoring of shipments involving goods stored in packaging incorporating dry ice cooling agents, SRIL-8 data loggers can be placed along with the goods without the device breaking down. No external probes are therefore required. The recorders can store up to 8,000 readings.  A special feature in the logger is the ability of the logger to background collect measured data, thereby ensuring that data is still available if the user forgets to activate the logger before placing it with the shipment.

Using a very hardy download interface and LogTag Analyser software, LogTag recorders have been found to be easily configurable.  Data download is also a breeze with the software providing an easy to use UI that shows the data as a graph or table.   The software also provides facilities for charting, zooming, listing data statistics and allows exporting the data to spreadsheet applications.

  • Ideal for monitoring dry ice shipments.  Can be placed within the shippers along with dry ice
  • Credit card sized case – thin enough to be easily mailed “letter rate”.
  • ‘Pre-Start’ logging – Logtag can be configured to record even if it has not been started.
  • Rated for a typical trip of 2 weeks duration at dry ice temperatures.
  • Push Button Logging start with optional delayed start or specific Time & Date start
  • Red Alert indicator indicates if readings are outside of preset limits.  Green indicator indicates if still recording and if readings within configured limits
  • Memory capacity of 8000 data points.
  • Real time clock records time & temperature simultaneously
  • Easy to use LogTag Analyzer software that runs on any PC.
  • Local Re-calibration facility available
