SKU : CI-203 Category :


The CI-203 Handheld Laser Leaf Area Meter is a highly portable laser scanner ideal for rapid and non-destructive leaf area measurement in any location. Measurements are made easily by sweeping the scanner over a leaf to yield seven different parameters: area, width, length, perimeter, shape factor, aspect ratio, and void count.

Researchers can use the CI-203 to make non-destructive measurements on leaves of living plants, enabling data collection on a leaf or plant throughout its life span. Graphical outline of the leaf shape is provided upon completing a scan, which provides verification that measurements are calculated accurately on even the most intricate leaf shapes. Built-in GPS tagging adds a location for each data point, and the removable Wi-Fi SD card provides an easy and fast way to download data to your computer. For rapid measurement of detached leaves, the CI-203CA conveyor attachment makes a perfect complement to the CI-203 and there is a discounted price for buying the two together.
