H-T277 4G GPS Temperature Monitoring Tracker
The H-T277 is a portable 4G GPS temperature monitoring terminal developed by Shenzhen Huwen Xinglian Technology Co., Ltd.Designed specifically for cold chain logistics, pharmaceutical distribution, fresh food delivery, warehousing, and high-value cargo transportation.This compact terminal integrates
temperature monitoring, satellite positioning, cellular communication, and data logginginto a single unit—requiring no complex wiring and enabling seamless deployment with cargo, insulated containers, refrigerated vehicles, or transport packaging.The H-T277 supports 4G Cat1 network connectivity and leverages multiple positioning technologies—including
BeiDou (BD), GPS, LBS, Wi-Fi, and Bluetooth—to ensure reliable location acquisition across diverse environments. Collected temperature and position data are automatically uploaded to a server or GPS/IoT management platform at configurable intervals, allowing managers to remotely monitor cargo routes and temperature trends in real time.High-Precision Temperature Monitoring
The H-T277 features an integrated high-precision temperature sensor with a measurement range of
-40°C to +85°C, achieving accuracy of±0.5°C within -20°C to +60°C.Users can configure custom upper and lower temperature thresholds based on cargo requirements. When temperature exceeds the preset limits, the device triggers an over-temperature alert and transmits it to the management platform—enabling rapid response to anomalies.
For pharmaceuticals, vaccines, fresh produce, frozen foods, and other temperature-sensitive goods, this real-time monitoring capability enhances traceability and compliance throughout the supply chain.
