Plant Spectral Analyzer is a compact instrument mainly used to measure plant reflectance, which can evaluate chlorophyll content through various reflectance coefficients
And other important features. Mainly used for: photosynthesis research; Plant Biology; Plant screening and field research; Coercion physiology; Agronomy and Forestry
Purpose:
Two standard versions (PRI&NDVI): PRI (Optical Reflectance Coefficient):
PRI (Optical Reflectance Coefficient) is a value calculated by assessing the emission of light at two wavelengths, 531 nm and 570 nm, from plant leaves
The efficiency of light energy utilization during plant photosynthesis can be used as a reference index for plant water stress. PRI is related to the lutein cycle
The epoxidation state is closely related and sensitive to changes in carotenoid content, which in turn reflects photosynthetic efficiency and CO2 uptake
PRI can be applied to the study of plant production and stress, as it is an indicator of input rate or water stress. PRI can measure photosynthetic efficiency and water stress index NDVI (Normalized Difference Vegetation Index)
NDVI (Normalized Difference Vegetation Index) is an important parameter reflecting the chlorophyll content of plants, which is calculated by assessing the emission of light at two wavelengths, 660 nm and 740 nm, from plant leaves
Features:
Compact and sturdy design, very suitable for outdoor environments, plant greenhouses, etc
5-inch color touch screen, easy to use
Non invasive non-destructive measurement
High capacity lithium battery, capable of continuous use for 8 hours
USB data transfer
Application:
Photosynthesis teaching and research; Plant Molecular Biology; Screening and field research of plants; Adversity physiology; Agriculture and forestry, etc.
