This LogTag requires a USB Interface to connect to a computer for configuration and reading data.
This specialist LogTag will record temperatures as low as -80°C – the temperature of dry ice. You can place the logger directly in with your dry ice shipment (no need for a probe) to log temperatures across the journey.
The logger is reusable and will last up to 1,000 hours at -80°C.
If you’re dealing with dry ice, such as the transportation of goods cooled by dry ice, the LogTag Dry Ice Recorder is the product for you. Directly monitor temperatures as low as -80°C with the battery capability to record for 1,000 hours at that temperature.
This logger doesn’t require a probe. Pack it directly in with your shipment for the most accurate measurements.
|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 for -30°C to 20°C. Better than ±1.2°C for -45°C to -30°C and 20°C to 40°C. Better than ±1.7°C for 80°C to -45°C. 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 for -80°C to 0°C. Less than 0.2°C for 0°C to 20°C. Less than 0.5°C for 20°C to 40°C. 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®.|
|Sensor Reaction Time||Typically less than 5 minutes (T90) in moving air (1m/s).|
|Recording Capacity||8000 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging.|
|Sampling Interval||Configurable from 1 minute to 18 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 (8000 readings), depending on computer or readout device used.|
|Environmental||IP65 (roughly equivalent to NEMA 4).|
|Power Source||3.6V low temperature chemistry Lithium battery.|
|Battery Life||Storage life of up to 12 months before ‘start’. Rated for up to 1000 hours of exposure to -80°C.|
|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).|

As the temperature drops, so does the life of your battery.
The LogTag Dry Ice Temperature Recorder is one of the only loggers that will even function at -78.5°C, the surface temperature of dry ice, but any electronic device operating at that temperature pays a price in battery life.
The device was previously rated at 1,000 readings, but now the fine print reads 1,000 hours at -80°C.
That’s quite a difference. If you’re sampling every five minutes, that equates to 12,000 readings, not 1,000.
Remember that the LogTag Dry Ice is a reuseable device, so your 1,000 hours are cumulative and may occur over the course of a year or two. In between uses, when the LogTag is at room temperature, the battery will last as long as a regular logger.
