Calibration Traceability
Apogee Instruments SQ-600 series ePAR sensors are calibrated through side-by-side comparison to the mean of
four transfer standard sensors under a reference lamp. The transfer standard sensors are recalibrated with a
quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST).
