INOLA series leaf area meter is a portable instrument that is easy to use and can be operated in the field. It can accurately, quickly, and non-destructively measure the leaf area and related parameters of leaves, and can also measure the area of harvested plant leaves and other flat objects. It is widely used in agriculture, meteorology, forestry, and other fields.
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.)
