QSO-S 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. It 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.

For use with the Em50 Data logger.

Conversion:

Sensors are calibrated for outside use.

Materials:

Anodized aluminum with acrylic lens.
