Portable Leaf Area MeterIt is a portable device used for rapid, accurate, and non-destructive measurement of plant leaf area and related parameters, widely used in the fields of agriculture, forestry, meteorology, and ecology research. Its core functions include measuring morphological parameters such as leaf area, leaf length, leaf width, perimeter, aspect ratio, and shape factor. Some models can also synchronously record auxiliary data such as environmental humidity and latitude and longitude. The instrument is based on the principle of photoelectric conversion, capturing the blade contour through a built-in optical system, and combining image processing technology to automatically separate the background and target object, ensuring measurement accuracy.
This device adopts a lightweight design and supports in vivo and ex vivo blade measurement. The operation process is simple: users only need to lay the blades flat on the measurement platform or clamp them in place, and simply touch the button to complete data collection. Some high-end models are equipped with full-color touch screens, which can intuitively display blade contours and analysis results, and support Bluetooth, Type-C interface or APP connection to achieve data cloud synchronization and export. In addition, the instrument has an adaptive design for leaf spine thickness, which can accommodate leaves of different thicknesses and avoid damage to plants.
Portable Leaf Area MeterThe product features mainly include the following aspects:
1. Measurement function
Fast and accurate: It can complete the measurement of blade area in a short time. Some instruments can also simultaneously measure and record parameters such as blade length, average width, and maximum width. The measurement results have high accuracy, such as the LI-3000C portable blade area meter, which can achieve a resolution of 1mm ² and an accuracy of<± 2% when the area is>50cm ².
Non destructive: It can directly measure the leaves on plants without picking, without affecting plant growth, and is beneficial for long-term monitoring of plant growth processes.
Multi type measurement: It can not only measure the area of various common plant leaves, but also adapt well to leaves with irregular shapes and varying thicknesses. It can also measure the area of picked plant leaves and other sheet-like objects.
2. Operation usage
Simple and convenient: Designed based on ergonomics principles, the operation is simple and easy to understand. Usually, simply place the blade into the measurement area or align the device with the blade, and press the button to complete the measurement. Some instruments are also equipped with one click analysis function, which can quickly obtain various parameters of the blade.
Visual operation: Equipped with a clear display screen, it can intuitively display measurement results and related data information. Some instruments also support viewing files on the screen or transferring data to a computer or printer through a data interface, facilitating data processing and analysis.
High degree of automation: The system can automatically separate the color of the collected object from the background, greatly improving the accuracy of data measurement and reducing human errors.
3. Portability
Compact size: The overall design of the instrument is compact, easy to carry, and can be easily used in fields, laboratories, and other places, suitable for measurement needs in different environments.
Lightweight: For example, the LI-3000C portable leaf area analyzer has a scanning head weight of only 680g and a controller weight of 2.0kg, which will not impose too much burden on the user.
4. Data Processing and Storage
Large capacity storage: Built in with a certain amount of storage space, it can store a large amount of measurement data, such as the LI-3000C portable leaf area meter with 2.1M flash memory that can store 65000-125000 measurement results.
Convenient data export: Supports transferring data to computers or other devices through USB interfaces, Bluetooth, and other methods for further data analysis and processing. It can also export data to Excel spreadsheets and other formats for data sharing and report writing.
5. Durability and stability
Excellent Material: The shell is generally made of sturdy and durable materials, with certain waterproof, dustproof, and anti drop properties, and can adapt to different working environments, such as complex field environments and daily laboratory use.
Strong battery life: Equipped with rechargeable batteries, a single charge can meet long-term usage needs. For example, the LI-3000C portable leaf area meter can work continuously for 12-15 hours.
