The SISCO portable leaf area meter, designed specifically for convenience and fieldwork, delivers precise, rapid, and non-destructive leaf area measurements. This versatile leaf area measurement device is suitable not only for live (in-situ) leaves but also for harvested leaves and other sheet-like materials. With excellent performance and easy operation, this leaf area scanner is widely used in agriculture, meteorology, forestry, and various scientific research fields.
Clear Display & Portable Integrated Design
- This leaf area meter utilizes advanced microcomputer technology combined with a high-contrast LCD screen, ensuring data remains visible even under strong outdoor light. The touch-enabled display makes reading measurements intuitive and effortless.
- The integrated design of the main unit and probe allows single-handed operation, making the leaf area meter lightweight and highly portable. Powered by a high-performance internal battery, it supports long-term continuous use without external power. With a built-in low-voltage indicator, this portable leaf area meter is especially suitable for outdoor measurement tasks.
Multi-parameter Measurement & Efficient Data Output
- Our leaf area measurement instrument offers a comprehensive range of functions, supporting parameters such as leaf area, average leaf area, leaf length, and leaf width. It can measure large leaves up to 1000 × 155 mm² and store 250 sets of data.
- The YMJ-B and YMJ-G leaf area meters feature an RS232 communication port for seamless data transfer to a computer. The YMJ-G model further integrates a high-speed GPS positioning module, automatically attaching time and geographic coordinates (longitude and latitude) when uploading data, significantly improving data management efficiency and traceability.
Applications
A leaf area meter is widely used in plant physiology to evaluate key processes such as photosynthetic efficiency and respiration. In plant pathology, it helps monitor disease progression by detecting changes in leaf characteristics. In agronomy, it provides data guidance for crop management, including irrigation and fertilization adjustments. In horticulture, a plant leaf scanner supports the selection of varieties with optimal leaf morphology and helps refine cultivation practices.

Details
Q1: What types of leaves can this portable leaf area meter measure?
A1: This portable leaf area meter offers broad applicability. It can accurately measure leaves from living plants—such as crop leaves growing in fields or fresh leaves from trees in forests—with ease. It also precisely measures leaf area and related parameters for harvested plant leaves. Additionally, it can measure other flat objects like thin plastic sheets or paper, provided their dimensions fall within the instrument's measurement range (width: 0~150 mm, length: 0~1000 mm).
Q2: What happens when the measurement data storage is full?
A2: This leaf area meter supports storing 250 sets of data. When storage capacity nears capacity, you need not worry about data loss. The instrument features an RS-232 communication interface (available on YMJ-B and YMJ-G models), allowing you to easily transfer stored data to a computer via this interface. After importing to a computer, you can further analyze, organize, and permanently store the data. Simultaneously, you can clear the instrument's internal storage to continue subsequent measurements, ensuring the device consistently records new data.
Q3: Does the battery life meet field usage requirements?
A3: This leaf area meter features a high-performance battery, eliminating the need for external power sources and offering great convenience in the field. Its strong battery endurance meets the demands of extended field measurements. Additionally, the device features a low-voltage indicator that alerts you promptly when battery power is low, giving you ample time to replace the battery or take other measures. This prevents measurement disruptions due to insufficient power, ensuring you can complete all field tasks smoothly.
Tips: How to quickly find a suitable location for leaf area measurement in the field?
Selecting an appropriate location is crucial when conducting leaf area measurements outdoors.
- First, consider lighting conditions. Choose areas with uniform and adequate illumination to avoid inaccuracies caused by excessively bright or dim light.
- Simultaneously, avoid areas with obstructions such as tree branches or large rocks, which could block leaves and lead to inaccurate measurements.
- Additionally, when measuring living leaves, select those in good health with no signs of disease or pest damage. This ensures measurements accurately reflect the plant's actual leaf condition.
