Calibration Traceability
Apogee Instruments SQ-600 series PFD sensors are calibrated through side-by-side comparison to the mean of four
transfer standard PFD sensors under a reference lamp. The transfer standard PFD sensors are recalibrated with a
quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST).
± 5 % (see Calibration Traceability below)
0.6 s, time for detector signal to reach 95 % following a step change; fastest data transmission
340 to 1040 nm ± 5 nm (wavelengths where response is greater than 50 %; see Spectral
± 2 % at 45° zenith angle, ± 5 % at 75° zenith angle (see Directional Response below)
