LogTag® TRIL-8/SRIL-8 Ultra-Low temperature data loggers with integrated sensor

LogTag® TRIL-8/SRIL-8 Ultra-Low temperature data loggers with integrated sensor


Transit monitoring of goods stored in packaging incorporating dry ice cooling agents

Product Summary

The LogTag® Dry Ice “Probe-less” Temperature Recorder operates, measures and stores up to 8000 temperature readings in temperature environments ranging from -80 °C to +40 °C.

Intended for use in transit monitoring of articles stored in packaging incorporating dry ice cooling agents.

Available in single trip (SRIL-8) and multiple trip (TRIL-8) versions.

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

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.

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 product incorporates an external temperature sensor uniquely arranged in a recess in the case. This arrangement protects the sensor from physical damage while retaining the faster response time normally associated with remote sensors.

Please note: An interface is required for configuration and reporting
