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 multi trip (TRIL-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.
|Sensor Measurement Range||-80°C to +40°C (-112°F to +104°F).|
|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.
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).
LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
|Sensor Reaction Time||Typically less than 5 minutes (T90) in moving air (1m/s).|
|Recording Capacity||8031 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging.|
|Sampling Interval||Configurable from 1 minute to several hours.|
|Logging Start Options||Push button start or specific date & time.|
|Recording Indication||Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator.|
|Download Time||Typically less than 5 seconds for full memory (8031 readings), depending on computer or readout device used.|
|Environmental||IP65 (roughly equivalent to NEMA 4).|
|Power Source||3.6V low temperature chemistry Lithium battery (Fixed).|
|Battery Life||Minimum storage life of 1 year before ‘start’ (if it is in hibernation mode)|
Single use version rated for a typical trip of 2 weeks duration at dry ice temperatures.
Multi-use version is rated for up to a total accumulative exposure of 1000hrs @ -80°C across multiple trips.
|Real Time Clock||Built-in real time clock.|
Rated accuracy ±25ppm @ 25°C (equivalent to 2.5 seconds/day).
Rated temperature coefficient is -0.034 ±0.006ppm/°C (I.e typically +/- 0.00294 seconds/day/°C).
|Size||86mm(H) x 54.5mm(W) x 8.6mm(T).|
