Product details















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 without damage measure the leaf area and related parameters of leaves, as well as measure the area of harvested 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 the blade, and integrates a GPS positioning system with an RS232 interface. It can import measurement data and positioning information into the computer at the same time, making it convenient for researchers to further process the data.
Difference between live leaf area analyzer/leaf area analyzer models:
| MODEL | Functional differences |
| YMJ-A | No computer interface, data can be stored and viewed on the host |
| YMJ-B | There is a computer interface that not only stores data on the host, but also transfers data to the computer. The software can be printed and converted to EXCEL format |
| YMJ-G | There is a computer interface and an added GPS positioning module, which can achieve synchronization of time, address, etc. during measurement |
Purpose:
The YMJ series leaf area measuring instrument is a portable device that is easy to use and can be used for field work. It can accurately, quickly, and without damage measure the leaf area and related parameters of leaves, as well as measure the area of harvested plant leaves and other sheet-like objects. Widely used in agriculture, meteorology, forestry and other departments.
Functional features:
1) The integrated design of the host and probe makes operation more convenient.
2) Adopting microcomputer technology and large LCD display.
3) High performance battery, no need for external power supply, low voltage display, more suitable for field measurement.
4) One time measurable large blade area (1000 * 155mm2)
5) Can store 250 sets of data (leaf area, leaf length, leaf width).
6) Multiple parameters of the blade can be measured, including leaf area, average leaf area, leaf length, and leaf width.
7) Communication interface: RSR232 interface, which can import data into the computer. (This feature is only available for B and G models)
8) GPS positioning: Integrated with high-speed GPS positioning module, the uploaded data comes with time and latitude and longitude information, making it easier to process data more effectively. (This feature is only available for G-type)
Technical parameters:
(1) Area unit: cm2
(2) Resolution: 0.01cm2
(3) Measurement error:<5%
(4) Width range: 0-150mm
(5) Length range: 0-1000mm
(6) Data recording: 0-250 groups
(7) Power supply: 4 No. 5 batteries
