CID Bio-Science: April 2015, Measuring Leaf Area

March 25, 2016 at 11:28 pm | Updated March 25, 2016 at 11:28 pm | 2 min read

For a plant scientist, the way leaf area and shape change in response to stress or environment can provide key insights into a study. CID Bio-Science makes it fast and easy to collect a host of data on leaf area including length, width, perimeter, ratio, and shape factor.
The CI-202 Portable Laser Leaf Area Meter is a pallet-style leaf area meter with a scan board that the leaf is placed on to be measured. The leaf is placed underneath a plastic cover sheet, which flattens and spreads the leaf for accurate measurements. 
The CI-203 Handheld Laser Leaf Area Meter—a wand-style leaf area meter—is perfect for long or thick leaves, as well as those with regular edges. To measure leaf area with the CI-203, sweep the leaf through the measuring wand, and the instrument instantly scans and calculates the leaf area, width, length, perimeter, shape factor and aspect ratio. The CI-203 also has an optional conveyor accessory for rapid, destructive measurements. This can be very useful to get through end-of-season mass sampling in a short amount of time. 
Did you know that our leaf area meters can be used for much more than leaves? See how researchers have creatively put leaf area meters to work for these applications:

Tips from Tech Support

Question: How do I keep my CI-202 and CI-203 Leaf Area Meters measuring accurately?
Answer: Cleanliness is key! Keep the scan window clean and free from debris, as well as the scan board and cover sheet on the CI-202. For the CI-203, wipe down the reflective material on the underside of the arm and clean the roller to keep it functioning at its best. Further accuracy adjustments can be made in the Setup menu to bring the length and width measurements back to within the accepted error range.
