YMJ-B plus portable laboratory leaf area meter

YMJ-B plus portable leaf area meter can instantly measure the area, circumference, length, width, aspect ratio, and shape factor of leaves. It can measure both detached and non-detached leaves. It is easy to operate and easy to carry. It can be linked to a computer to export data, and the software can generate data and graphical reports. It is widely used in leaf growth analysis in agriculture, forestry, horticulture and breeding work, and provides an important reference for the selection of high-quality agricultural varieties.

Features

1. Touch color screen: The portable leaf area meter uses an RGB touch color screen with dual display of data and 

graphics, which is intuitive and clear.

2. Graphical presentation of data: The measured blades will visually display blade outline images and blade 

morphology data indicators.

3. Multiple data compensation modes: According to the specific conditions of leaf shape, there are three selection 

modes: "no compensation, rectangular compensation, and triangle compensation", which can improve the data and 

make the calculation results more accurate.

4. Support automatic data collection: automatic and manual data collection modes can be selected to adapt to 

different measurement scenarios.

5. Charging and data transmission two-in-one: The device uses a Type-C interface. When the data cable is connected

 to a computer, it can be charged and exported excel data tables and leaf charts, and the data can be processed 

directly on the computer.

6. Convenient data management: The mobile app can obtain real-time measurement data and instrument historical 

measurement data, and the data can be selected individually or in batches to be exported in excel form.

7. Diverse and convenient transmission methods: It supports Bluetooth connection to mobile app and Type-C 

connection to computer for data transmission.

8. Large-capacity storage: The built-in storage area can store the latest 1,000 pieces of data; the extended storage 

area can store more than 1 million pieces of data; the validity of the data can be directly determined on the host to 

reduce subsequent data screening work.

9. Data loss prevention: The device automatically saves the data of each measurement result and reminds when the 

battery is low to prevent data loss due to unexpected shutdown of the device.

10. With GPS positioning function: obtain sample coordinates while measuring, and clarify the corresponding area 

of the sample for easy tracking.

11. Automatically shut down when there is no operation: The device can be set to automatically shut down when 

there is no operation for a fixed time to save power.

12. Super battery life: Equipped with 5Ah lithium battery, it can work in the field for 16 hours when fully charged.
