Yaxin-1242 Portable Leaf area Meter

The Yaxin-1242 Leaf Area Meter uses advanced CCD technology to allow researchers a precise and convenient way to measure leaf area (or the areas of leaf-like objects). One high-quality CCD scanner, data logger, and display are all enclosed in a single, hand-held palette unit weighing approximately 1.5Kg. Researchers can perform non-destructive measurements on leaves of living plants by simply sliding the scanner over the leaf.
