The LogTag® Dry Ice “Probe-less” Temperature Logger operates, measures and stores up to 8000 temperature readings in temperature environments ranging from -80°C to +40°C (-112°F to +104°F).
Intended for use in transit monitoring of articles stored in packaging incorporating dry ice cooling agents.
Available in single trip (SRIL-8) version.
Using the LogTag® Interface and LogTag’s freely available companion software LogTag Analyzer, the LogTag® Dry Ice Temperature Logger 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.

|Operating Temperature Range||-80°C to +40°C (-112°F to +104°F).|
|Storage Temperature Range||-20°C to +40°C (-4°F to +104°F).|
|Rated Temperature Reading Accuracy||Better than ±1°C (±1.8°F) for -30°C to +20°C (-22°F to +68°F).
Better than ±1.2°C (±2.1°F) for -45°C to -30°C (-49°F to -22°F) and +20°C to +40°C (+68°F to +104°F).
Better than ±1.7°C (±3.1°F) for -80°C to -45°C (-112°F to -49°F).
Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
Accuracy figures can be improved by recalibration.
|Rated Temperature Reading Resolution||Less than 0.1°C (0.2°F) for -80°C to 0°C (-112°F to +32°F).
Less than 0.2°C (0.4°F) for 0°C to +20°C (+32°F to +68°F).
Less than 0.5°C (0.9°F) for +20°C to +40°C (+68°F to +104°F).
Please see the Rated Native Resolution chart below.
LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
