A next-generation remote temperature monitoring device designed for continuous, real-time cold chain tracking during the storage and distribution of food, medicines, vaccines, blood, reagents, biological products, and biological sample tissues. The U-COOL-PRO advances beyond the U-COOL with two pluggable temperature sensors (versus one), an additional pluggable door switch sensor, 4G/3G/2G network support, and an optional PT100 sensor for cryogenic monitoring from −200°C to +150°C — covering the full spectrum from ultra-low temperature to high-heat environments.

The device automatically connects to the UCool EMS platform upon power-on, transmitting temperature data via 4G/3G/2G cellular networks with no complex configuration required. The two external pluggable digital sensors enable simultaneous monitoring of two distinct points — in the same environment or across separate equipment — and each sensor can be individually replaced without replacing the central device. The optional PT100 sensor extends the measurement range to −200°C to +150°C, making the U-COOL-PRO compatible with ultra-low temperature freezers, cryogenic storage, and high-temperature chambers.

The integrated environmental sensor simultaneously monitors ambient temperature (−10°C to +55°C) and relative humidity, providing a complete diagnostic of storage conditions. The built-in audio-visual alarm (buzzer + light) triggers immediately upon any detected temperature deviation. The pluggable door switch sensor records door-opening events, adding an operational traceability layer not available on the U-COOL.

The rechargeable battery delivers over 10 days of autonomy per charge, ensuring uninterrupted monitoring in environments without continuous power access. Historical data can be exported via USB for up to 30 days of records, and geographic positioning is performed via LBS (Location Based Service) — fully functional indoors where conventional GPS is ineffective.

Applications

The U-COOL-PRO is designed for clinical, pharmaceutical, and research laboratories, hospitals, blood banks, medicine distributors, and refrigerated logistics operators requiring remote monitoring of multiple points or environments with extreme temperature requirements — both cryogenic (ultra-low temperature freezers and liquid nitrogen storage) and high-temperature (incubators, stability chambers, climatic chambers).

The combination of two pluggable sensors, a door switch sensor, and an optional PT100 probe makes the U-COOL-PRO particularly suited for complex installations where single-point monitoring is insufficient and operational event traceability must be documented for regulatory compliance and quality management purposes.
