PAR Photon Flux Sensor

The PAR Photon Flux sensor measures the Photosynthetic Photon Flux (PPF) in μmol m^-2 s^-1. from a field of view of 180 degrees. Decagon's PAR Photon Flux sensor is completely water proof, submersible, and designed for continuous outdoor use.

The cosine-corrected head has a domed diffusion disk for improved self-cleaning. The diffusion disk is composed of characterized pigments for improved spectral response. Accurate measurement depends on cleanliness of the lens, and installation at horizontal (180°). A leveling plate is included for accurate installation.
