Fresh Keeper-1 is a reusable temperature and humidity data logger designed for long-term environmental monitoring. The temperature and humidity logger sensor supports a maximum working time of up to 999 days and can store up to 35,000 readings, making it suitable for extended transportation and storage applications.
Monitoring parameters can be configured using Freshliance free software. With the integrated USB interface, users can directly connect the logger to a computer to generate encrypted and irreversible PDF/CSV reports, without additional software. Temporary reports are also supported for interim data checks.
Parameters configurable
Monitoring parameters can be programmed using Freshliance free configuration software before deployment.
High accuracy and large capacity
This USB temperature and humidity recorder features built-in sensors with a temperature accuracy of ±0.5℃ and a humidity accuracy of ±3% RH, and supports up to 35,000 readings.
Mark function
Up to 9 marks can be added during the monitoring process to record key events.
Intuitive LCD screen
The LCD screen allows users to easily view operating status, Max., Min., and Average values, alarm status, remaining working days, battery level, and other trip statistics.
Super-long battery life
Designed for long-term monitoring, the reusable temperature and humidity data logger can operate for up to 999 days.
Automatic PDF/CSV data report
By connecting the logger to a PC via USB, encrypted PDF or CSV reports are generated automatically without software. Temporary reports are available when needed.

Fresh Keeper-1 industrial temperature data logger combines large memory capacity, long battery life, and easy operation, making it suitable for cold chain transportation, storage, and other processes involving pharmaceuticals, food, and other temperature-sensitive products.
For frozen food, maintaining appropriate temperature thresholds is essential to limit microbial growth. For fruits, vegetables, and flowers, proper environmental monitoring helps prevent premature ripening and preserves freshness, quality, and shelf life.
Temperature- and humidity-sensitive products must be carefully monitored and documented during handling and storage to ensure food safety, product quality, and regulatory compliance, especially for highly perishable goods such as dairy, seafood, meat, poultry, and floral products.
With this USB temperature and humidity data logger, users can track environmental data, respond promptly to alarms, and analyze recorded data through irreversible reports to continuously improve transportation and storage conditions.
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.
