Precise, Rapid Measurements of Large or Small Leaves

The 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.

  • Area, Length, Maximum Width, Average Width
  • A single lens provides adjustable resolution of 0.1 or 1 mm2
  • High accuracy and repeatability, and fast, continuous operation for large quantities of samples with individual or cumulative area recorded
  • Large (25 cm wide, 2.5 cm thick with 1 mm2 resolution) or small (<1 cm2 area when using 0.1 mm2 resolution) leaves or other objects, including needles
  • Quiet belt system with adjustable press roller to flatten curled leaves
  • Data are shown on the instrument LED display or on the computer screen using Windows® software to collect and store data via RS-232 or USB

Accuracy
Sample Area
Resolution 10 cm2 3 cm2 1 cm2 0.3 cm2
1 mm2 ± 2.0% ± 3.0% ± 6.0% ± 10.0%
0.1 mm2 ± 1.0% ± 1.5% ± 3.0% ± 5.0%

Combined accuracy and precision to 99% confidence with correct calibration on verifiable shapes. Better accuracy can be achieved by calibrating the LI-3100C and/or placing the leaf on the middle section of the belt. Use the 0.1 mm2 resolution for conifers, roots and other similar objects and expect the accuracy to be about 5% less than normal leaves.

Applications

Biological applications include measuring small leaves with precision similar to that obtained when measuring large objects. A wide variety of leaves can be measured; from small samples such as wheat, rice or alfalfa, to larger samples such as corn, tobacco, and cotton. Projected area of certain sizes of conifer needles can also be measured (consult LI-COR).
