PolyPen RP 400


PolyPen RP 400 features a complete system for measurement of spectral reflectance of an internal light source (Xenon incandescent lamp 380 - 1050 nm) from leaves, as well as measurements of transmittance and absorbance of any external light source. In addition, PolyPen incorporates formulas of commonly used reflectance indices (e.g. NDVI, NDGI, PRI, Greenness Index, etc.) into its software. Measured data are instantly displayed in graphs or data sheets on the device screen display. They are also stored in the device memory for later re-collection or transfer onto a PC.

PolyPen RP 400 is manufactured in two versions: 
PolyPen RP 400 UVIS with minimum declared range 380 to 780 nm (790 nm covered) 
PolyPen RP 400 NIR with minimum declared range 640 to 1050 nm.

PolyPen RP 400 is a self-contained system that runs on Li-Ion rechargeable battery and does not require any external PC. It features an innovative user interface with integral computer, full color touch screen display, built-in light source, and a sample holder - non-destructive leaf clip. The device is delivered with a Spectralon standard for the highest diffuse reflectance values (included in the price).
