living Leaf Area tester 

introduction:
The XM series of leaf area meter is easy to use, portable instruments can work in the field. Accurate, rapid, noninvasive measurement of the blade of the leaf area and related parameters can also be harvested plant leaves and other sheet objects area measurement. Widely used in agriculture, meteorology, forestry and other departments.
host, probe the integration of design, more convenient operation.
