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.
Case Study - Assessment of Attractiveness of Plants as Roosting Sites for the Melon Fly, Bactrocera cucurbitae, and the Oriental Fruit Fly, B. dorsalis
In this study, Dr. Grant McQuate, Researcher with the USDA Agricultural Research Service (ARS) in Hilo, Hawaii, investigates the attractiveness of different plant species as roosting hosts for melon fly and oriental fruit fly, B. dorsalis. This analysis was performed using the CI-203 Handheld Laser Leaf Area Meter to measure leaf areas of different plant species, permitting the standardization of fly catch by leaf area.
