QSO-S PAR Sensor
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.
soft cloth at frequent intervals. Small changes in the level of
the sensor can also cause errors. Make sure that the top of
the domed sensor body is kept horizontal. Use the included
leveling plate to ensure the sensor level.
The sensor is designed for continuous outdoor use, and is
completely water proof and submersible. The QSO-S is
supported by the LSM1 Light Sensor Meter for PAR Sensors
or Decagon’s data loggers Em50 or Em50G.
Installation:
The sensor should be mounted with the cable pointing
toward the nearest magnetic pole. For example: in the
Northern Hemisphere, point the cable toward the North
Pole. In the Southern Hemisphere, point the cable toward
the South Pole.
Common Errors:
The biggest error is often caused by dirt on the lens of the
sensor. The domed top is self-cleaning, but measurement
accuracy will be improved if the lens is wiped with a clean,
