Fresh Tracker 20 4G real-time data recorder is engineered for seamless integration into confined spaces in the cold chain transportation and logistics. Its 89 × 59 × 21 mm slim design allows it to be perfectly embedded in thermal boxes, vaccine transport containers and incubators, etc, not occupying valuable space.
User-friendly App and cloud platform are provided for real-time data visibility into your shipments, such as temperature, humidity, geolocation, illumination and shock. The cloud-based terminals enable informed decision-making and full compliance with strict regulations. The 4G real-time data logger supports breakpoint resume, remaining data logging and storing in offline mode and re-uploading data to Freshliance Cloud after network restoration. Besides, API service is optional for streaming the cloud data seamlessly to your existing management systems.
If any environmental deviations, immediate notifications will be sent via SMS, email, or App push. The multi-channel alert system allows you to address potential issues, significantly reduce risks of spoilage and ensure product safety from origin to destination.
With LBS/GPS/WiFi positioning and geolocation mapping, this real-time data logger allows operators to monitor geolocation and environmental conditions simultaneously on a single screen, and replay historical travel paths. It guarantees that you never lose sight of your cargo, enhancing supply chain visibility and security, and enables optimized route planning. The travel route can be replayed, helping you optimize routes and improve efficiency.
In addition to 4G connectivity, Fresh Tracker 20 transport real-time data logger also features built-in Bluetooth connectivity. It can be connected with the dedicated Bluetooth printer to effortlessly print hard copies of compliance reports within seconds, no computer, mobile phone or internet connection required. This feature significantly simplifies handover procedures at delivery points and ensures transparent and efficient documentation transfer between transporters and receivers.
Multi-level administration access is optional for cloud platform. Organizations can assign customized roles and permissions to different team members, protecting sensitive information while enabling centralized oversight of multiple shipments and users. This hierarchical structure is especially valuable for organizations that manage large fleets or complex cold chains.
Fresh Tracker 20 real-time temperature and humidity data logger is suitable for the transport and logistics of pharmaceuticals, vaccines, lab samples, diagnostic kits, clinical trial materials and other sensitive products. Fresh Tracker 20 4G data logger is a good guardian in the medical transport to safeguard product quality and efficacy and strict compliance with standards.
