1. Integrated structural design with built-in GPS module, 4G module, and external SD card, capable of accurately measuring the geographical information of the tested location. The interface displays the measured environmental parameters, stored data, and the latitude and longitude of the measurement point. Through the built-in GPRS, it can upload the environmental factor measurement data of the tested point with a single click.

2. The device is compact, aesthetically pleasing, easy to operate, reliable in performance, and extremely convenient for field use. After connecting to sensors, the main unit can manually store and record data or automatically store and record data by setting the sampling interval via the main unit.

3. Large LCD display tracks and records the values and groups of all measured environmental factors, as well as low voltage alerts. The main unit has a built-in large-capacity storage device capable of storing 300,000 data points and features automatic data storage protection in case of power failure.

4. After inserting sensors into the main unit, it automatically identifies them. Sensors have good consistency and can be freely combined according to requirements. Interfaces for sensors with different parameters can be interchanged without affecting measurement accuracy.

5. The instrument has multi-channel automatic detection expansion functionality, enabling simultaneous synchronous detection of multiple sensors.

6. The central station software is powerful, enabling unified collection, processing, and analysis of data. Data can be exported to a computer via the USB interface at any time and stored as an Excel spreadsheet file, generating data curves for further processing by other analysis software. It includes a function to highlight data exceeding set thresholds, with color-coded warnings for out-of-range data, which can serve as a basis for environmental assessments.
