Poly-PlantPen RP 400

Poly-PlantPen RP 400 is a handheld instrument designed for measurement of leaf reflectance. It features an innovative user interface with integral computer, full color touch screen display, built-in light source, and a sample holder. RP 400 is a self-contained system that runs on Li-Ion rechargeable battery and does not require any external PC. It is equipped with a leaf clip for gentle leaf holding at a fixed angle. The leaf clip also provides reference standard for calibration of the light source and detector. Integrated software is capable of automatic calculation of all common vegetation indices, such as, NDVI, PRI, Greeness Index, TCARI, ZMI, Simple Ratio Index, and many others. Measured data are instantly displayed in graphs or data sheets and can be easily exported to a PC via USB cable.
