Real-time Temperature Monitoring for Liquid Nitrogen Transport

Liquid nitrogen cold chain operates at -196°C ultra-low temperature, critical for preserving biomaterials, vaccines and advanced samples. Yet it faces severe challenges: extreme temperature drift risks, offline blind spots, lack of real-time location visibility, and slow alerts that risk costly cargo damage. Traditional loggers cannot meet ultra-low temperature, real-time, positioning and geofencing demands. Now Freshliance proudly introduces Fresh Tracker 10-ETU real-time ultra-low temperature data logger— an all-in-one real-time temperature monitoring solution for safe liquid nitrogen transport.

Fresh Tracker 10-ETU real-time ultra-low temperature data logger works with external probes that go down to -196°C (±0.5℃ (-100℃~+80℃)), ideal for liquid nitrogen environments. It transfers data to the cloud continuously via 4G connectivity. This allows for remote real-time monitoring of temperature, humidity, illumination, geolocation and shock on a phone or computer. Real-time alerts are triggered instantly via SMS, email and APP push plus on-device LED indicators and LCD display, so you respond timely before issues escalate.

Powered by GPS/LBS/WiFi positioning, it provides clear geolocation mapping for full journey visibility. Geofencing lets you set virtual zones and get alerts automatically when shipments enter/leave restricted areas, strengthening route control and handover management. Flight mode supports air transport while offline caching preserves up to 30,000 records, auto-reuploaded when 4G connectivity resumes.

Compact, rugged and rechargeable, Fresh Tracker 10-ETU real-time ultra-low temperature data logger runs reliably for up to 120 days at 60min upload interval. With API service, it supports seamless data integration into your customized IoT cold chain systems and platforms. For liquid nitrogen cold chain that demands zero compromise on safety and traceability, Fresh Tracker 10-ETU protects your high-value cargo with real-time intelligence, and is well suited for reusable long-haul monitoring.
