Description
This compact wireless temperature sensor provides accurate and reliable temperature monitoring for cold chain, pharmaceutical, food processing and industrial applications. Featuring a detachable stainless steel temperature probe and long-range LoRaWAN® connectivity, it enables continuous remote monitoring without requiring communication or power cabling.
Designed for demanding environments, the sensor measures temperatures from -40°C to 125°C, making it suitable for refrigerators, freezers, cold rooms, laboratories and temperature-controlled storage. The detachable probe simplifies replacement and calibration while maintaining long-term measurement accuracy. Its IP67-rated enclosure protects against dust and water ingress, ensuring reliable operation in harsh indoor and outdoor environments.
Local storage retains up to 4,000 measurements, automatically retransmitting data when communication is restored to maintain a complete audit trail. Configurable high, low and abrupt temperature change alarms provide early warning of temperature excursions, helping protect valuable products and maintain regulatory compliance.
Integrated with the Sense It monitoring platform, the sensor provides live dashboards, historical trends, automated reports and multi-channel alerts. NFC configuration, optional magnetic mounting and a battery life of up to 9 years make installation and maintenance fast and straightforward.
