Logtag® TREL-8

Low Temperature recorder with external probe -80°C to +40°C

Logtag® TREL-8 is easily configured for recording conditions including delayed start, sampling interval, number of readings and configuration of conditions to activate the ALERT indicator.
It is intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments.

Readings are downloaded using LogTag® Analyzer which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as Excel.

The Red Alert indicator provides an immediate indication, without access to a PC, if any readings are outside the limits specified at the time the unit was configured. Green OK indicator provides immediate visual confirmation, without access to a PC, that the unit is operating.

 

Product Highlights

  • Alert indicator – indicates if readings are outside of preset limits
  • OK indicator indicates if still recording and if readings within configured limits
  • Inspection mark in log by push button
  • Push Button Logging start
  • Rapid Download! Takes only seconds to download recordings
  • ‘Pre-Start’ logging – Logtag® can be configured to record even if it has not been started.
  • High performance at low cost
  • Credit card sized case – thin enough to be easily mailed “letter rate”.
  • Real time clock records time & temperature simultaneously
  • Easy to use LogTag®Analyzer software that runs on any PC configures LogTag® for recording then downloads resulting data for analysis. Data can also be exported to formats compatible with other applications such as Excel
  • Re-calibration to achieve higher accuracy possible
  • High quality gold plated remote sensor connector
  • Interchangeable Probes – LogTag® remote temperature probes are interchangeable.
