I. Product Introduction
The YMJ-PC Plant Leaf Area Meter consists of a high-resolution scanner + backlight panel device + PC software. It captures images through scanning and analyzes them via PC software. In addition to generating leaf morphological parameters, it also produces disease spot and insect damage parameters, including residual leaf analysis and leaf color analysis. The plant leaf area meter is widely used in agriculture, forestry, grassland, horticulture, and other fields, effectively addressing the need for rapid, convenient, and accurate measurement of phenotypic parameters for large quantities of plant leaves.

II. Features
1. Ultra-high-resolution scanner: 22-megapixel high resolution, faster analysis speed, foldable/telescopic design.
2. Diverse analysis methods: Supports single leaf analysis, multi-type leaf simultaneous analysis, and field in vivo analysis, with algorithms generating over a dozen leaf parameters.
3. Clear scanning without reflection: Equipped with a backlight panel and pressure plate. The backlight panel offers multi-level stepless dimming, and the pressure plate has anti-reflection functionality, minimizing the impact of light on leaves.
4. Fully automatic calibration: Automatically calibrates and calculates after scanning images, eliminating the need for manual calibration.
5. Manual correction for more accurate results: For leaves with complex shapes, manual correction of leaf length and width is possible to improve analysis results. The leaf area meter allows manual marking to measure straight-line distances or the perimeter and area within a specified region.
6. Multi-functional analysis for more precise measurements: The software includes features such as automatic calibration, hole filling, petiole segmentation, target area analysis, disease spot and insect damage analysis, residual leaf matching, leaf color grading, leaf color analysis, customizable serration height, customizable minimum leaf length, and display of bounding rectangles.
7. Exportable and appendable analysis data: Analysis marked images can be exported, and statistical analysis results can be exported or appended to Excel sheets for secondary analysis.
8. Powerful data processing capabilities: Capable of batch automated analysis of over 100 images at once, automatically saving analyzed images and results. Multi-leaf analysis of the same image can output average values.
9. Enhanced data security: Utilizes dynamic QR code + hardware dongle encryption to prevent loss of images and statistical data.
10. Convenient data viewing: Images and analysis results can be uploaded to the instrument cloud platform, accessible via app and web for viewing and downloading data.
