A portable remote temperature monitoring device designed for continuous, real-time cold chain tracking during the storage and distribution of vaccines, medicines, blood products, reagents, and biological materials. WHO prequalified (PQS code: E006/060), the U-COOL transmits data via GPRS/2G/4G to a centralized remote management platform, combining analytical precision, geographic traceability, and intelligent data management in a single rugged, portable device.
The external NTC sensor automatically measures, records, and transmits temperature data across a range of −40°C to +65°C, with precision of ±0.5°C between 0°C and +65°C, and ±1°C between −40°C and 0°C. The integrated environmental sensor simultaneously monitors ambient temperature (−10°C to +55°C) and relative humidity (0%RH to 99%RH), delivering a complete diagnostic of storage or transport conditions. Setup is fully user-defined, and data uploads to the platform automatically as soon as the device is powered on.
The remote management platform tracks temperature, location, and signal strength in real time, generating multiple data analysis reports with geolocation via Google Maps and LBS (Location Based Service). Upon any temperature deviation, an integrated audio-visual buzzer and LED light issue an immediate alert — with no operator input required to identify the event.
The rechargeable battery (charging voltage: 5–12 V; current ≤ 1.5 A; capacity: 6,000 mAh) delivers over 10 days of continuous operation per charge. Historical data can be exported via USB for up to 30 days of temperature records. IP65 protection makes the device waterproof, shockproof, and anti-collision, suitable for the most demanding logistics and field environments.

Applications
The U-COOL is designed for national vaccination programs, pharmaceutical distributors, refrigerated logistics operators, blood banks, clinical laboratories, and research institutions requiring continuous, real-time thermal traceability during the storage and distribution of temperature-sensitive products. The device is compatible with a wide range of environments: refrigerated trucks, cold rooms, cold packs, incubators, refrigerators, and freezers.
It is particularly valuable for field operations and last-mile logistics in developing regions, where remote cold chain visibility is critical and conventional monitoring infrastructure is limited — the precise context for which WHO prequalification was granted.
