In the high-stakes world of pharmaceutical and biologics logistics, cold chain monitoring is mission-critical. Every degree matters—temperature deviations can threaten cold chain compliance, compromise drug efficacy, and risk patient safety. The global cold chain temperature monitoring market, valued at $167 billion in 2023, is forecast to surpass $240 billion by 2030, driven by biologics, mRNA vaccines, and gene therapies.
W18L: Rugged Cold Chain Tracking and Monitoring Solution
The W18L tracker is a next-generation cold chain temperature monitoring system that combines cold chain tracking with IoT intelligence. It provides real-time GPS, temperature, humidity, and light sensing in a durable, IP67-rated waterproof design. With an operating range from –20 °C to 75 °C, the W18L ensures reliable cold chain control across diverse environments—from cryogenic shipments to ambient deliveries.

This cold chain monitoring solution integrates cold chain telematics and cold chain sensors to deliver full visibility for pharmaceutical shipments.
Why Bluetooth Temperature and Humidity Tags Matter
While the W18L tracks the overall environment, Bluetooth temperature monitoring devices for cold chain applications enable precise cool chain monitoring inside individual cartons or pallets.
Key benefits:
-
Granular Temperature Mapping – Multiple BLE tags detect hot and cold spots, enhancing cold tracking accuracy during transportation temperature monitoring.
-
Wireless Data Collection – The W18L aggregates BLE tag data and uploads it via cellular networks—eliminating complex wiring in cold track setups.
-
Automated Alerts – If any tag detects a deviation, the cold chain monitoring system sends real-time notifications, ensuring rapid corrective action.
This layered approach is essential, as average cold chain temperature variance can exceed 2–3 °C due to poor insulation or frequent door openings—risks that centralized sensors may miss.
End-to-End Cold Chain Control
| Phase | Risk | W18L + BLE Tags Solution |
|---|---|---|
| Cryo Storage | Maintaining sub-zero temperatures | Tags near vials trigger instant alerts for cold chain compliance |
| Transit | Uneven cooling in the vehicle | BLE tags detect hot spots; W18L streams GPS + cold chain tracking and monitoring data |
| Warehouse | Ambient fluctuations | Cold chain sensors monitor each pallet to maintain stability |
| Last-Mile | Heat exposure in urban delivery | Tags detect rising temps; proactive rerouting keeps cold chain temperature within range |
