Portable and rapid non-destructive measurements of leaves area, length, width etc


Product Details

The CI-203 Laser Leaf Area Meter is the most portable and easy-to-use instrument of its kind. This rugged instrument non-destructively measures leaf area, length, width, and perimeter, plus counts voids and calculates geometric shape factor and ratio. A leaf image is reconstructed from the scanner data, providing verification of the scan quality in the field.

The CI-203 can perform for hours at a time in the field, and data is easily transferred to a computer by SD card or USB connector. 



  • Improved consistency of measurements
  • Graphic display and rendering of leaf images for verification of a successful scan and auditing of data
  • Built in GPS tagging to provide location data for each measurement
  • Non-destructive measurements
  • No calibration required
  • One-Touch Data: Simply sweep the CI-203 over a leaf to yield six measurement parameters: area, width, length, perimeter, shape factor, and aspect ratio
  • Durable and lightweight
  • Improved consistency of measurements
