1. Integrated design of the main unit and probe for easier operation.  

2. Utilizes microcomputer technology with a large LCD display.  

3. High-performance battery eliminates the need for external power supply; low voltage indication makes it ideal for field measurements.  

4. Capable of measuring a large leaf area (1000 × 155 mm²) in a single measurement.  

5. Can store 250 sets of data (leaf area, leaf length, leaf width).

6. Measures multiple leaf parameters: leaf area, average leaf area, leaf length, and leaf width.  

7. Communication interface: RS-232 interface, enabling data transfer to a computer. (This feature is available only on Pro and Plus models.)  

8. GPS positioning: Integrated high-speed GPS positioning module, with uploaded data automatically tagged with time and latitude/longitude information, facilitating more efficient data processing. (This feature is available only on Plus models.)
