Click to ViewThe LI-3100C Area Meter is designed for efficient, exacting measurements of both large and small objects. User-selectable area resolution of either 1 mm2 or 0.1 mm2 is available without having to change optics. This versatility provides the flexibility necessary for diverse project requirements.

  Working Principles
Click to ViewThe LI-3100C is a rugged bench-top instrument designed to quickly digitize the area, length, and width of leaves. It features two transparent conveyer belts that rotate to move leaves across a scanning bed. The LI-3100C is ideal for rapidly measuring large quantities of harvested leaves. The LI-3100C records the area of individual leaves and quickly computes cumulative area for a group of leaves, making it easy to compare treatments or experimental groups.

  User Instructions
Simply place a leaf on the lower transparent belt, and it is automatically conveyed across the scanning bed. A press roller flattens any curled edges and feeds the leaves properly between the transparent belts before they enter the scanner, ensuring the full area is represented in each measurement. Leaves are ejected from the scanning bed after they are measured.
