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).|

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).|
Compliance and Certifications
Protect your Dry Ice LogTag from bumps and scrapes with a sturdy plastic case.
The design of the enclosure minimises the effects of thermal lag caused by additional casing.
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.
To use this LogTag, you will need a USB interface and the LogTag Analyzer software installed on your PC.
This LogTag uses the same Reader as other LogTags, so if you already have one, it will work with these models.
If not, make sure you order one as well. As a bonus, we include the latest free LogTag Analyzer software on USB.
