PlantPen Chlorophyll Meter NDVI and PRI

PlantPen PRI 210 and PlantPen NDVI 310
PlantPen is a reflectance-based device that provides a convenient and low-cost method for measuring the relative photosynthetic pigment content of a leaf sample. PlantPens measure and calculate particular reflectance indices to assess chlorophyll content, photoprotective carotenoids, and other important characteristics in living foliage. Two standard versions of PlantPen measure the most common indices: Photochemical Reflectance Index (PRI) and Normalized Difference Vegetation Index (NDVI). Measured data are stored sequentially in FluorPen's internal memory. The comprehensive FluorPen 1.1 software provides data transfer routines and many additional features for data presentation in tables and graphs.
The PlantPen model PRI 210 measures the photochemical reflectance index (PRI) by comparing leaf reflectance in two narrow wavelength bands centered near 530 nm and 590 nm. The PRI is sensitive to changes in carotenoid pigments that are indicative of changes in photosynthetic light use efficiency, CO2 uptake rate, and as a reliable index of water stress. As such, it is used in vegetation productivity and stress studies.
The PlantPenmodel NDVI 310 measures the Normalized Difference Vegetation Index (NDVI), which is an important indicator of chlorophyll content in plants. The plant leaf pigment chlorophyll strongly absorbs visible light (0.4 to 0.7 µm) for use in photosynthesis. The cellular structure of leaves, on the other hand, strongly reflects near-infrared light (0.7 to 1.1 µm). Differences in plant reflectance in visible and near-infrared wavelengths are used to calculate the NDVI index. NDVI is directly related to the photosynthetic capacity and therefore the energy absorption of plant canopies.
