Leaf Area Measurement & LAI

• CI-110 Plant Canopy Imager

The new CI-110 combines hemispherical canopy photography and image analysis with light measurement to non-destructively calculate leaf area index (LAI) and other canopy parameters. The self-leveling digital camera takes 150 degree images of plant canopies for hemispherical photograph analysis. The 24 photosynthetically active radiation (PAR) sensors in the arm of the instrument can be used for an alternative measurement of LAI, to assess current radiation levels of the site, and to evaluate sunflecks. The updated, ergonomic design is paired with a 7" capacitive touch screen, a trigger with delayed image release for crisp images, and the ability to add or exchange filters over the camera lens.

• CI-202 Portable Laser Leaf Area Meter

The CI-202 Portable Laser Area Meter uses advanced laser technology to provide researchers with a precise and convenient way to measure leaf area. The high-resolution laser scanner, data logger, and display are all enclosed in a durable, handheld scanner and detachable palette. The CI-202 is used to perform non-destructive measurements on the leaves of living plants by placing the leaf on the palette and sliding the scanner over the leaf, enabling collection of data from the same plant, or even the same leaf, throughout its life span. The transparent, protective sheath on the palette makes it easy to capture precise leaf area measurement on tender or intricate leaves.

• CI-203 Handheld Laser Leaf Area Meter

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.
