Applications


Fresh Keeper-IUT dry Ice Sensor Temperature USB Data Logger can be used for a wide range of applications such as monitoring dry ice shipments, sea or air freight, distribution, storage and freezing, pharmaceuticals, frozen foods, and shipping containers. This stand-alone USB Temperature Sensor does not require any additional probes.


Fresh Keeper-IUT dry Ice USB Sensor Temperature Data Logger is suitable for in-transit records of biopharmaceuticals, life sciences, biological samples, blood cold chain, diagnostic reagents, including biological reagents, molecular reagents, COVID-19 reagents, and cell biology agents during low temperature environment. 


Products such as biologics and vaccines have a short shelf life, so the temperature change during transportation should be controlled in time. Our USB Temperature Sensor with a real-time large temperature display is ideal for the pharmaceutical industry and biologics.

Freshliance Tools


Freshliance Tools is a PC software designed for easy configuration, data retrieval, and analysis of Freshliance USB data loggers. Once a logger is connected via USB, the software automatically detects the device and displays key information such as device ID, battery level, logging interval, device status and start mode. Users can view temperature and humidity trends in interactive graphs, access detailed data logs, and get statistics including max/min/average values and MKT. 


The software supports flexible report export in PDF, CSV, TXT  or PNG format across multiple languages, and allows full configuration of logging parameters, alarm thresholds, time zones, and report settings. The software also supports data comparison of multiple devices on a same chart, allowing users to easily identify discrepancies and analyze performance across different loggers.
