Leaf Area Meter (YMJ-A)

Host Introduction:

The 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 undamaged measure the leaf area and related parameters of leaves, as well as measure the area of picked plant leaves and other sheet-like objects. Widely used in agriculture, meteorology, forestry, and other fields.

The instrument can directly measure the length, width, and area of blades, and integrates GPS positioning and 4G wireless transmission system. It adds a Type-C interface, which can import measurement data and positioning information into both computers and cloud data platforms, making it convenient for researchers to further process the data.

Differences in models of live leaf area measuring instruments/leaf area measuring instruments:

Model and functional differences

YMJ-A has no computer interface and can store and view data on the host

YMJ-B has a computer interface, which not only stores data on the host, but also transfers data to the computer. The software can print and convert it to Excel format

YMJ-G has a computer interface and adds 4G wireless transmission and GPS positioning module, which can achieve synchronization and transmission of time, address, etc. while measuring

Functional characteristics of live leaf area measuring instrument/leaf area measuring instrument:

1) The integrated design of the host and probe makes operation more convenient.

2) Adopting microcomputer technology, LCD large liquid crystal display.

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

4) Large blade area can be measured at once (2000 * 155mm2)

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

6) Multiple parameters of the blade can be measured: leaf area, average leaf area, leaf length, and leaf width.

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

8) Communication interface: Type-C interface, which can import data into the computer. (This feature is only available for B and G models)

9) GPS positioning: Integrated with high-speed GPS positioning module, uploaded data comes with time and latitude information, making it convenient and effective for data processing. (This feature is only available for G-models)

10) 4G wireless transmission: Measurement data can be uploaded to the cloud platform in real time, and data such as measurement time and leaf area can be viewed. Histogram analysis can be performed on different parameters. Data can be exported in Excel form, printed online, displayed according to the selected time period, analyzed in tables, histograms, and downloaded online. (This function is limited to G-type only)
