LogTag Dry Ice Temperature Logger with External Probe

$165.00$214.50 inc GST

Monitor Dry Ice containers without opening them

Insert the probe into your container and attach your LogTag Dry Ice temperature logger. The LED Alert will tell you at a glance if the temperature has risen above your limit.

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 Model TREL-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 Accuracy With 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 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®.
