Freshliance Fresh Tracker 4G Real-Time Cold Chain Loggers

Zhengzhou Freshliance Electronics Corp., Ltd is a Chinese maker of IoT temperature and humidity data loggers and online environmental monitoring, founded in 2015 and based in the Airport Economy Zone of Zhengzhou. It serves cold chain storage and transport of fresh produce, food, pharmaceuticals and vaccines, offering single-use loggers such as Fresh Tag, real-time 4G and Wi-Fi loggers, LoRa tags and gateways.

The Fresh Tracker 10 rides with shipments and records temperature, humidity and optional light and shock, with built-in or external probes down to -196 °C. It uploads over 4G LTE Cat1, locates the cargo via LBS, Wi-Fi or GPS, supports a flight mode for air freight and stores up to 30,000 readings per probe when offline. Data appears on a web platform and the Ttracker mobile app with graphs, MKT analysis and an e-map, and alerts arrive by SMS, e-mail or app push. The compact Fresh Tracker 20 targets vaccine and medical cold boxes and adds Bluetooth report printing for handover checks.

• Multi-sensor logging: temperature and humidity with optional light and shock sensors.
• Wide probe range: external probes from -30 °C up to +200 °C and down to -196 °C.
• 4G and positioning: LTE Cat1 upload with LBS, Wi-Fi or GPS location.
• Flight mode: keeps recording with the modem off during air transport and uploads afterwards.
• Cloud and Ttracker app: real-time data, graphs, MKT analysis, e-map and remote configuration.
• API: system integration and secondary development for ERP or customer platforms.

• A fruit exporter in Vietnam can track reefer trucks to Chinese border gates with live temperature and location.
• A vaccine distributor can place Fresh Tracker 20 units in cold boxes and print handover reports at clinics.
• A frozen food company can monitor cold rooms and delivery vans through one cloud account and API.

• Battery life of up to 120 days at a 10-minute logging and 60-minute upload interval covers long sea and land routes.
• Offline storage of up to 30,000 readings per probe with automatic re-upload prevents data gaps in dead zones.
• Instant SMS, e-mail and app alerts let shippers react to excursions during transit.
• Bluetooth printing on Fresh Tracker 20 gives drivers and inspectors on-site reports for cargo handover and spot checks.

Affordable 4G real-time loggers are replacing download-only devices as exporters and pharma distributors demand live visibility and proof of temperature compliance. Vietnam's fresh fruit, seafood and vaccine flows, including cross-border trucking to China, create demand for low-cost trackers with location data.

Freshliance was founded in 2015 in Zhengzhou, China, and describes itself as an ISO 9000 certified enterprise. CE certificates are listed for several Fresh Tag and logger models. Its site cites projects and tests with JBS, BASF and Zhengzhou CDC, vaccine cold chain projects in Spain, and exhibitions including the Canton Fair and ASIA FRUIT LOGISTICA.
