About This Product

■SummaryThis is a package that measures LAI manually at any timing. A portable LAI analyzer that comes with everything you need including a sensor, 2ch data logger, gun grip, and transport case.

When PAR (400-700nm) and NIR (700-1,000nm) are reflected and absorbed by chlorophyll within a leaf, the ratio of the transmitted light has a correlation with LAI.In other words, we adopted a spectroscopic measurement method (Patent No. JP5410323B22014.2.5). It is possible to measure LAI stably regardless of the weather, and achieves highly reproducible measurements only by measuring inside the canopy, without measuring the light environment outside the canopy.

By installing this device together with a data logger, annual changes in LAI can be measured unattended, and if you use a portable type, you can carry it around and measure over a wide area.

■Features・True LAI measurement that responds only to areas containing chlorophyll
・True LAI measurement is possible by neglecting PAI (PAI: measurement value including dead leaves, branches, trunks, etc.)
・The world's only sensor that measures the light transmitted through the tree canopy at a viewing angle of 180 degrees with wideband PAR=400-700nm and IR=700-1,000nm, and adopts a relationship in which the intensity ratio of PAR and IR correlates with LAI.
- Much more accurate than the fisheye lens type
・Portable and portable
