Fresh Keeper-IUT Dry Ice Ultra Low Temperature Data Logger is specially designed to monitor and record temperatures in ultra-low temperature environments. Capable of accurately measuring ultra-low temperatures down to -90°C (-130°F), it is an ideal temperature controller for ultra-low shipments requiring frequent temperature sampling intervals. This dry ice temperature data logger operates stably and has high accuracy. The temperature data it monitors and records is accurate and reliable. It is very suitable for ultra-low temperature transportation such as dry ice.

Fresh Keeper-IUT Dry Ice Ultra Low Temperature Data Logger temperature monitoring range is between -90℃ to +70℃ (-130°F ~ 158°F), with an accuracy of ±0.5℃/0.9°F (-30°C ~70°C/-22°F~158°F); ±1℃/1.8℉ (others). After the trip is over, the device can automatically generate a temperature data report for the entire trip when connected to a computer or mobile phone. The operation is very simple and practical.
