Tzone is showcasing the TT19SI 4G real-time temperature, humidity and location sensor at Fruit Attraction, one of its best-selling models

The TT19SI, one of the best-selling models in the series, is primarily designed to meet the practical needs of cold-chain transport and enables real-time monitoring of temperature, humidity, location, light and vibrations. Data is transmitted to the system’s platform via the 4G network, facilitating centralised management and data traceability. The device also features a USB port that allows data reports to be exported in PDF format.

In terms of connectivity, the TT19 is compatible with 4G/5G networks worldwide and, as a fallback option, with 2G networks, ensuring a stable connection across different countries and regions.

A wide range of cold chain monitoring devices

In addition to the TT19 series, Tzone offers a wide range of cold chain monitoring devices, such as Bluetooth temperature and humidity loggers, LoRa wireless sensors, temperature and humidity transmitters, and LoRa gateways, capable of covering a variety of scenarios including storage, transport and distribution. With 20 years’ experience in the sector, Tzone has its own R&D and production capabilities, as well as its own factory, which fully guarantees product quality and delivery times.

Tzone will be at stand 4A31 at the exhibition
