Measurements: Photosynthetically Active Radiation (PAR)
Measure Photosynthetically Active Radiation
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.
Weatherproof for Long-Term Use
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.
