Complete cold chain logistics solution

Traditional single-point trackers fail to detect temperature differences and blind zones inside refrigerated containers, easily causing undiscovered cargo spoilage and untraceable transit data. Our GPT46 4G LTE-M GPS Tracker + BTT01 Temperature Beacon paired solution solves these pain points perfectly, delivering all-round, real-time location and multi-spot temperature monitoring for full cold chain visibility.

How the Dual-Device Solution Works

This system adopts a professional gateway + sensor master-slave linkage design. The GPT46 acts as the core Bluetooth gateway installed on refrigerated trucks or containers, while multiple mini BTT01 temperature beacons are placed on pallets, cargo boxes and blind monitoring areas. BTT01 continuously collects on-site temperature data and transmits it to GPT46 via Bluetooth. The master device synchronizes real-time GPS location data and multi-point temperature data to the cloud platform for unified viewing and intelligent alarm management.

Core Device Advantages

GPT46 4G LTE-M GPS Tracker

A industrial-grade 4G LTE Cat M1 tracker built for cold chain fleet management. It supports multiple GNSS + Wi-Fi/LBS hybrid positioning for high-precision location tracking. Equipped with vibration/collision/light/temperature multi-alarm functions, and long battery life, enabling stable unattended long-distance transportation monitoring. Its exclusive Bluetooth gateway function supports multi-beacon simultaneous connection for full-coverage data collection.

BTT01 Mini Temperature Beacon

Ultra-small, wiring-free Bluetooth temperature logger for cold chain monitoring. With high-precision temperature sensing, long standby battery life and stable Bluetooth 5.0 transmission, it adapts to low-temperature cold chain environments. Flexible to deploy on any cargo position, it eliminates monitoring blind zones and makes up for the defects of single-point temperature detection of traditional trackers.

Key Application Scenarios

Ideal for full-process monitoring of pharmaceutical shipments, fresh produce, seafood and frozen goods. Widely applicable to refrigerated truck fleets, cross-border container transportation and batch cold chain asset supervision. It provides complete, exportable temperature and location records to meet logistics compliance, and insurance claim requirements.

Solution Highlights

Zero monitoring blind zones, real-time abnormal temperature alarms, 24/7 unattended monitoring, easy wireless deployment and low maintenance costs. This integrated solution minimizes cold chain cargo loss, standardizes transit monitoring and greatly improves your cold chain logistics credibility and operational efficiency.
