Improved Battery Life

Because this logger sits outside the super-cold environment, its battery life is the same as regular LogTags

Visual Alerts

If the temperature inside the package rises above the alert level, the red LED will flash, giving you a visual notification that there has been a problem.

Easy to use

The LogTag is so simple to set up and use that you'll be an expert in no time. We have a full LogTag training program on our site

Know what the temperature is without opening the container

Our probe-less Dry Ice LogTags are great for their convenience, but this probe model has its own advantages.

Importantly, you can get an instant gauge of the temperature inside the packaging – flashing red means there is a problem.

Also, battery life is better than the direct contact model.


Product ModelTREL-8.
Sensor Measurement Range-80°C to +40°C (-112°F to +104°F).
Operating Temperature Range-20°C to +40°C (-22°F to +104°F).
Storage Temperature Range-10°C to +55°C (14°F to +131°F).
Rated Temperature Reading AccuracyWith the logger case sitting in an environmental temperature between 0°C and 50°C:
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 ResolutionLess than 0.1°C for -80°C to 0°C.

Do you have the USB Reader Interface?

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.
