Handheld Leaf Area Meter YMJ-G

Handheld Leaf Area Meter YMJ-G

Host Introduction:

        YMJ series living 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 of leaves and related parameters, and can also measure the area of harvested plant leaves and other flaky objects. It is widely used in agriculture, meteorology, forestry and other parts.

       The instrument can directly measure the length, width and area of leaves, and integrates GPS positioning as well as 4G wireless transmission system, and adds 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 the majority of researchers to further process the data.

Living leaf area meter/leaf area meter model difference:

Model Function Difference

YMJ-A without computer interface, data can be stored and viewed on the host computer.

YMJ-B has a computer interface, in addition to storing data on the host computer, but also can transmit data to the computer, the software can be printed and converted into EXCEL format.

YMJ-G has a computer interface, and increase the 4G wireless transmission and GPS positioning module, measurement can be achieved at the same time as the time, address and other synchronisation and transmission.

Live leaf area meter/leaf area meter functional features:

(1) Host, probe integrated design, more convenient operation.

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

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

(4) One-time can measure a larger leaf area (2000 * 155mm2)

5) 5000 groups of data can be stored.

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

7）Built-in calibration module, the user can be calibrated according to different use of the environment

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

(9) GPS positioning: integrated high-speed GPS positioning module, upload data with time, latitude and longitude information to facilitate more effective data processing. (This function is limited to G model)

10) 4G wireless transmission: Measurement data can be uploaded to the cloud platform in real time, you can view data such as measurement time, leaf area, etc., you can do histogram analysis of different parameters, support data export in the form of EXCEL tables, support data printing online, you can display data according to the selected time period, support data analysis in tables, histograms, etc., and download online. (This function is limited to G type)
