The portable leaf area tester is more suitable for living measurement of long and narrow leaves, and can obtain the leaf area, length, width, aspect ratio, leaf circumference and shape factor parameters. It can be linked to the computer to export data, and the software can generate data and graphic reports for easy management and analysis.
Instrument introduction:
YMJ-B portable leaf area meter is also called portable leaf area meter . It is a kind of live leaf area measuring instrument that is easy to use and can work in the field. The instrument can measure the leaf area and related parameters of leaves accurately, quickly and without damage, and can also measure the area of picked plant leaves and other sheet objects. It can be widely used in agriculture, meteorology, forestry and other departments.
Features of portable leaf area meter:
