Calibration Traceability:
Apogee SQ series quantum sensors are calibrated through side-by-side comparison to the mean of four
Apogee model SQ-110 or SQ-120 transfer standard quantum sensors under high output T5 cool white
fluorescent lamps. The transfer standard quantum sensors are calibrated through side-by-side
comparison to the mean of at least three LI-COR model LI-190 reference quantum sensors under high
output T5 cool white fluorescent lamps. The reference quantum sensors are recalibrated on a biannual
