Calibration Traceability

Apogee MQ series quantum meters 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 schedule with a LI-COR model 1800-02 Optical Radiation

Calibrator using a 200 W quartz halogen lamp. The 1800-02 and quartz halogen lamp are traceable to the National

Institute of Standards and Technology (NIST).
