Wireless Temp & Humidity Tracker.Complete cold chain logistics solution, real time location with GPS tracking, Temperature and humidity recordings

Reliable location and environmental monitoring are core to modern cold chain, medical logistics and asset management. To meet diverse tracking demands, we proudly launch our new flagship wireless tracker — the GPT45-M, strengthening our professional advantages in temperature and humidity monitoring solutions.

Our newly upgraded GPT45-M wireless tracker is engineered for high-demand scenario monitoring, it is with built-in temperature and humidity sensor, leveraging our core strengths in environmental tracking solution development to deliver reliable, multi-functional monitoring performance.

This innovative tracker adopts dual GPS/GNSS and Wi-Fi positioning technology, achieving high-accuracy positioning whether in open outdoor spaces or complex indoor and semi-indoor environments. It supports full-band LTE CATM1, NB-IoT networks with 2G fallback mechanism, guaranteeing stable and continuous data transmission even in areas with weak network signals. The built-in sensitive temperature and humidity sensors capture real-time environmental data, realizing 24/7 uninterrupted monitoring for tracked assets.

Equipped with powerful Bluetooth capability, the GPT45-M can act as a host tracker, supporting Beacon scanning temperature and humidity data uploads to expand monitoring coverage flexibly. What makes it stand out is the optional external PT1000 low-temperature probe interface, which enables professional ultra-low temperature monitoring, solving the pain points of conventional trackers that fail to adapt to extreme cold working environments.

Portable and tool-free for easy installation, this tracker boasts excellent adaptability, with strong adaptability for diverse deployment scenarios. It is perfectly suited for food cold chain transportation, drug , low-temperature commodity storage, and other critical scenarios requiring strict temperature and humidity control.

With integrated multi-positioning, full-network connection, intelligent environmental monitoring and expandable low-temperature detection, the GPT45-M is a cost-effective, high-performance tracking device for reliable, efficient and cold chain monitoring management.

Beyond standard cold chain product , we also provide customized hardware and solution services to tailor vehicle tracking, asset monitoring devices to meet varied client requirements.
