Freshliance — 4G Real-Time Temperature, Humidity & Geolocation Data Logger
Fresh Tracker 10 is a 4G data logger for real-time temperature, humidity, geolocation, illumination and shock monitoring. The logger records real-time and history data during the whole logistics process and transfers the data to Freshliance Cloud. The geolocation data is provided based on LBS, WiFi or GPS positioning.
All data are accessible via mobile APP and cloud platform. Flight mode is configurable for air transport. It is an ideal instrument for logistics and quality control.

The real-time data recorder monitors temperature, humidity, geolocation, illumination and shock in real time and transfers the monitoring data to Freshliance Cloud via 4G network with the configured uploading interval. Particularly, an E-map is provided on both the mobile APP and cloud platform based on configurable LBS base station or GPS service for users to track geolocation in real time.
The 4G wireless data loggers come with two operation terminals, mobile APP and cloud platform, enabling users to remotely configure and control the loggers, and track all monitoring data in real time. Besides, they feature powerful data summarization and processing functions, helping users more in data management and decision making.
The transport real-time data logger will not stop recording and storage during offline mode. And the data that is not successfully uploaded during network failure can be automatically re-uploaded after network recovery.
An alarm will be notified via the LED indicator on the device and remote SMS/Email messages instantly.
The device can be freely configured. In addition to start delay, logging interval, uploading interval, and alarm settings, etc., flight mode can be also set as needed. If it is set, the device will automatically enter flight mode at the preset start time. In this mode, the device only records data and does not upload data (the 4G module is turned off and there is no network signal). When the end time is up, the device will automatically exit the mode and resume normal operation after uploading historical data.
Multilevel administration access provides multiple levels of security to customers. As permitted, individuals are responsible for specific aspects during data monitoring, helping customers identify and address issues more quickly and reducing the risk of errors or non-compliance.
Both the APP and web platform are password protected.
It is designed to buffer readings against temporary air temperature shifts caused by opening doors or loading coolers and accurately simulate the thermal changes experienced by products stored in the monitored environment.
It is ideal for vaccines, pharmacies and walk-in coolers, etc.
Fresh Tracker 10 is a real time temperature and humidity data logger with geolocation, based on IOT platform. It is suitable for the cold-chain logistics and storage of fruits and vegetables, drinks, fresh produce, dairy products, vaccines, etc.
The most important aspect of the cold chain is to control the temperature and humidity within a proper range, so as to maximize product performance and prolong product life cycle. With this logger, the user can remotely get real time temperature and humidity data via our free APP and web platform and take specified corrective actions to minimize the loss.
