Applications

Monitoring of articles stored at very low temperatures such as in dry ice type environments, where a remote probe is beneficial.

Product Summary

The LogTag^® Low Temperature Remote Probe Recorder measures and stores up to 8000 temperature readings over -90 °C to +40 °C measurement range from associated interchangeable LogTag^® ST10 type remote probe temperature sensor (available in lengths up to 3 meters).

Intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments.

Using the LogTag^® Interface and LogTag’s freely available companion software LogTag^® Analyzer, the LogTag^® is easily configured for recording conditions including delayed start, sampling interval, number of readings and configuration of conditions to activate the ALERT indicator.

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.

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.
