Shenzhen Tzone Digital Technology Co., Ltd. is introducing its upgraded real-time monitoring device, the TT19SE 4G Temperature, Humidity & Location Data Logger, at the upcoming Transport Logistic exhibition in Munich, Germany, from June 2 to 5, 2025. This device aims to tackle the critical challenges of cold chain logistics, where even minor fluctuations in temperature or humidity can cause spoilage of perishable goods.
The company has 19 years of experience in the industry and manages everything from research and development to production in-house, ensuring both product quality and timely delivery.
Mr. Liao, Chairman of Tzone, highlighted the importance of the technology during this busy period, saying, “It is currently the peak season for fruits and vegetables in the northern hemisphere. In warehousing and logistics, temperature and humidity data loggers play an increasingly vital role in helping customers reduce losses and increase profits.”
The TT19SE captures real-time data on temperature, humidity, location, light exposure, and vibration, transmitting it via a 4G network to a backend system for continuous monitoring and analysis. All data is securely stored in the cloud and can be accessed or downloaded as PDF reports through USB, providing full cold chain visibility that enhances transport efficiency and reduces product losses. The device also detects conditions under low light and motion, protecting goods throughout transit.
Built with advanced sensors, the TT19SE incorporates a high-performance SHT30 sensor and supports connection to an external PT100 probe, offering a wide temperature detection range from -200°C to +200°C. It also features light-sensing capabilities up to 64,000 lux and vibration monitoring up to 16G, allowing it to accurately detect physical shocks and exposure to intense light during transportation.
Regarding connectivity and tracking, Mr. Liao explained, “In terms of positioning, the device not only supports GPS but also LBS base station tracking and route playback, ensuring full traceability of goods during transit.” The device is compatible with global 4G and 5G networks and includes a 2G fallback option to maintain stable connections across different regions.
The TT19SE offers a battery life of up to 120 days and is designed for single use, eliminating the need for charging or retrieval after deployment. Beyond this product, Tzone also provides a comprehensive range of cold chain monitoring solutions, including Bluetooth and LoRa wireless sensors, transmitters, and gateways, covering the full supply chain from storage to delivery.
