Leaf Area Index Meter

Leaf Area Index Meter

Product Description
The FG-811 Leaf Area Index Meter which also called plant canopy analyzer is a high-performance, portable instrument designed to measure Photosynthetically Active Radiation (PAR) and Leaf Area Index (LAI) within plant canopies. Featuring advanced multi-probe array technology, it delivers rapid, precise readings of canopy light conditions, ensuring reliable data for agricultural research, forestry management, and ecological monitoring. With its user-friendly design and proven accuracy, the FG-811 is an essential tool for scientists and professionals seeking to better understand and optimize plant growth environments.

 

After actual testing and result comparison, the test results of FG-811 and ACCUPAR LP-8 are very close.

· Cost-effective alternative to leading international model of ACCUPAR LP-80

· Comparable performance to premium international instruments

· Delivers performance matching global standards at a more accessible price
