The model QSO-S PAR Photon Flux sensor measures the Photosynthetic Photon Flux (PPF) in μmol m-2 s-1 from a field of view of 180 degrees. The diffusion disk is composed of characterized pigments for good spectral response.
The sensor is designed for continuous outdoor use, and is completely water proof and submersible.
Accurate measurement depends on cleanliness of the lens and installation at horizontal (180°). The sensor head has a domed diffusion disk to reduce the need for frequent cleaning. A leveling plate is included for accurate installation.
