Click to ViewIt can measure leaf area of any crop having leaf size within the below mentioned specification. Sample size for recording leaf area Width: 1.5 mm minimum to 25.0 – 30.0 cm maximum Thickness: Up to 2 cm or more, Length : Up to 2-2.5 m or more Scanning Area: 1 mm2 Resolution : 1 mm X 1 mm 0.1mm2 Resolution : 0.300 mm W x 0.333 mm L

  Working Principles
Click to ViewSamples are placed between the guides on the lower transparent belt and allowed to pass through the LI-3100C. As the sample travels under the fluorescent light source, the projected image is reflected by a system of three mirrors to a scanning camera. This unique optical design results in high accuracy and dependability. An adjustable press roller flattens curled leaves and feeds them properly between the transparent belts. This provides for accurate measurement of small grasses, legumes, aquatic plants and similar types of leaves. As samples pass under the light source, the accumulating area in mm2 is shown on the LED display or on a computer screen when using the Windows® software. Calibration adjustments are easily accomplished using a standard area calibration disk (included) and turning the calibration screw located near the display. A wide variety of leaves can be measured, ranging from larger samples such as maize, tobacco, and cotton to smaller samples such as wheat, rice or fingermillet. Small leaves or leaf discs are measured with the same precision as larger leaves.

  User Instructions
Type of analysis - Individual Leaf area as well as collective leaf sample, Leaf length, Leaf widthThe instruction to use the equipment is very easy. Switch on the leaf area meter. Switch on the lamp. The digital display board should be zero before recording the leaf area. Put the leaf sample on the lower conveyer belt. The leaf area will be displayed on the digital display board.
