Handheld Leaf Area Meter

Host Introduction:

YMJ series live leaf area measuring instrument is a newly developed product. It is a portable instrument that is easy to use and can work 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 picked plant leaves and other sheet-like objects. It is widely used in agriculture, meteorology, forestry and other sectors.

The instrument can directly measure the length, width and area of the leaf, and integrates GPS positioning and 4G wireless transmission system, and adds a Type-C interface, which can import the measurement data and positioning information into the computer and cloud data platform at the same time, which is convenient for researchers to further process the data.

Differences between living leaf area meter/leaf area meter models:

Functional features of living leaf area meter/leaf area meter:

1) Integrated design of host and probe, more convenient to operate.

2) Adopting microcomputer technology, large LCD display.

3) High-performance large-capacity battery, no external power supply required, low voltage display, sustainable measurement is more suitable for field measurement.

4) Can measure a large leaf area at one time (2000*155mm2)

5) Can store 5000 sets of data (leaf area, leaf length, leaf width).

6) Can measure a variety of leaf parameters: leaf area, average leaf area, leaf length, leaf width.

7) Built-in calibration module, users can calibrate according to different usage environments

8) Communication interface: Type-C interface, data can be imported into the computer. (This function is only limited to B and G models)

9) GPS positioning: integrated high-speed GPS positioning module, uploaded data comes with time, latitude and longitude information, convenient and more effective data processing. (This function is only available for G model)

10) 4G wireless transmission: The measurement data can be uploaded to the cloud platform in real time, and the measurement time, blade area and other data can be viewed. The bar chart analysis of different parameters can be performed, and the data can be exported in the form of EXCEL tables, and the data can be printed online. The data can be displayed according to the selected time period, and the data can be analyzed in tables, bar charts, etc., and downloaded online. (This function is only available for G type)
