Calibration Traceability
Apogee MQ series ePAR meters 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 200 W quartz halogen
lamp traceable to the National Institute of Standards and Technology (NIST).
380 to 760 nm ± 5 nm (wavelengths where response is greater than 50 %)
± 5 % at 75° zenith angle (see Cosine Response below)
-0.11 ± 0.04 % per C (see Temperature Response below)
Anodized aluminum body with acrylic diffuser
0 to 50 C; less than 90 % non-condensing relative humidity up to 30 C; less than 70 % non-
condensing relativity humidity from 30 to 50 C; separate sensors can be submerged in water up
