•Incoming and reflected PPFD over and under
plant canopies in greenhouses, in fields, and in
growth chambers
•Aquatic environments including salt water
aquariums and freshwater lakes and streams
UNIQUE DESIGN
Cost-effective, original quantum sensors work well for broadband radiation sources. The patented, dome-shaped aluminum head is cosine-corrected, self-cleaning, and fully-potted for a waterproof design.
ACCURATE, STABLE MEASUREMENTS
Cosine-corrected with directional errors less than ± 5 % at a solar zenith angle of 75°. Long-term non-stability less than 2 % per year.
CALIBRATION TRACEABILITY
Apogee SQ sensors are calibrated through side-by-side comparison to the mean of four transfer standard sensors under a reference lamp. The reference sensors are recalibrated with a quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST).
