GENERAL DESCRIPTION
The PlantPen model PRI 200 measures Photochemical Reflectance Index (PRI) in two narrow wavelength
bands centered close to 525 nm and 592 nm. The photochemical reflectance index (PRI = (R525–
R592)/(R525+R592)) correlates with the epoxidation state of xanthophyll cycle pigments and photosystem
efficiency in many studies under diverse conditions, such as different 1. PRI is sensitive to changes in carotenoid
pigments that are indicative of photosynthetic light use efficiency, the rate of carbon dioxide uptake, or as a
reliable water-stress index. As such, it is used in studies of vegetation productivity and stress.
The PlantPen model NDVI 300 measures Normalized Difference Vegetation Index, which is an important
indicator of chlorophyll content in plants. The pigment in plant leaves, chlorophyll, strongly absorbs visible light
(from 0.4 to 0.7 µm) for use in photosynthesis. The cell structure of the leaves, on the other hand, strongly
reflects near-infrared light (from 0.7 to 1.1 µm). The differences in plant reflectance in the visible and nearinfrared wavelengths is used to calculate NDVI index as follows: NDVI=((NIR-VIS)/((NIR+VIS)), where VIS and
NIR stand for the spectral reflectance measurements acquired in the visible (red) and near-infrared regions,
respectively. NDVI is directly related to the photosynthetic capacity and hence energy absorption of plant
canopies 2. The NDVI 300 device compares reflected light at two distinct wavelengths, 660 and 740 nm.
PlantPen models (PRI 200-B, PRI 200-U, NDVI 300-B, NDVI 300-U) incorporate one of the two offered
communication modules: Bluetooth or USB cable. FluoPen 1.0 software provides visualization and data transfer
routines to a computer.

LEAF CLIP AND THE PROTECTIVE RUBBER PAD
The optical part of the PlantPen is covered with a self-adhesive rubber pad that protects the optics from dirt or
moisture. The damaged or dirty pad can be easily removed by tearing it off from the surface. To affix a new
one, just remove the sheeting and stick the pad on cleaned and dried surface. Be sure that you placed the pad
properly and that you did not cover the optical window.
BATTERIES
The PlantPen operates from four AAA single-use or rechargeable batteries. They may be easily replaced by
unscrewing the cover of the battery holder on the rear of the instrument. Battery life is approximately 48 hours
when the PlantPen is operated continuously.

THEORY AND REFERENCES
PRI - PHOTOCHEMICAL REFLECTANCE INDEX
The Photochemical Reflectance Index or PRI is a reflectance measurement. The PRI is sensitive to changes in
carotenoid pigments (e.g. xanthophyll pigments) in live foliage. Carotenoid pigments are indicative of
photosynthetic light use efficiency, or the rate of carbon dioxide uptake by foliage per unit energy absorbed. As
such, it is used in studies of vegetation productivity and stress. Because the PRI measures plant responses to
stress, it can be used to assess general ecosystem health using satellite data or other forms of remote sensing.
Applications include vegetation health in evergreen shrublands, forests, and agricultural crops prior to
senescence. PRI is defined by the following equation using reflectance (ρ) at 531 and 570 nm wavelength:
The values range from -1 to 1.
NDVI - NORMALIZED DIFFERENCE VEGETATION INDEX
Normalized Difference Vegetation Index or NDVI is an important indicator of chlorophyll content in plants.
The device compares reflected light at two distinct wavelengths, 660 and 740 nm.
The NDVI is calculated from these individual measurements as follows:
where VIS and NIR stand for the spectral reflectance measurements acquired in the visible (red) and nearinfrared regions, respectively These spectral reflectances are themselves ratios of the reflected over the
incoming radiation in each spectral band individually, hence they take on values between 0.0 and 1.0. By
design, the NDVI itself thus varies between -1.0 and +1.0. It should be noted that NDVI is functionally, but not
linearly, equivalent to the simple infrared/red ratio (NIR/VIS). The advantage of NDVI over a simple
infrared/red ratio is therefore generally limited to any possible linearity of its functional relationship with
vegetation properties (e.g. biomass). The simple ratio (unlike NDVI) is always positive, which may have practical
advantages, but it also has a mathematically infinite range (0 to infinity), which can be a practical disadvantage
as compared to NDVI. Also in this regard, note that the VIS term in the numerator of NDVI only scales the
result, thereby creating negative values. NDVI is functionally and linearly equivalent to the ratio NIR / (NIR+VIS),
29
which ranges from 0 to 1 and is thus never negative nor limitless in range.But the most important concept in
the understanding of the NDVI algebraic formula is that, despite its name, it is a transformation of a spectral
ratio (NIR/VIS), and it has no functional relationship to a spectral difference (NIR-VIS).

PSI also offers out-of-warranty repairs. These are usually returned to the customer on a cash-ondelivery basis.

WEAR & TEAR ITEMS (such as sealing, tubing, padding, etc.) are excluded from this warranty. The
term WEAR & TEAR denotes the damage that naturally and inevitably occurs as a result of normal use
or aging even when an item is used competently and with care and proper maintenance.
