Applications
Fresh Keeper 1 temperature humidity recorder features large memory capacity, long battery life, high waterproof class and easy operation. With 9 marks and 6 alarm points configurable, the logger can be used for cold chain transportation, storage and other processes of pharmaceuticals, food, etc.
For frozen food, it is very important to keep the growth of microbes as low as possible by maintaining temperature threshold values.
For fruits and vegetables, the most important thing is to prevent them from ripening too early. Fruits, vegetables, and flowers are highly perishable commodities that require proper environmental monitoring in post-harvest processing to maximize freshness, quality, and shelf life from the field to the table.
The environmental condition of temperature-sensitive products must be carefully monitored and documented during handling and storage, to ensure food safety, quality, and longer shelf life, especially for highly perishable products such as dairy, seafood, meat, poultry, and floral products.
With this USB temperature humidity logger, you can be in control of temperature/humidity data and timely make adjustments according to alarms, so as to reduce losses and ensure product safety. And with an irrevocable report, you can study the changes in temperature/humidity and analyze the reasons, so as to gradually improve production, transportation and storage environment.

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.
