Apogee Instruments MQ-510 User Manual

SPECIFICATIONS
Calibration Traceability
Apogee MQ series quantum meters are calibrated through side-by-side comparison to the mean of four transfer
standard quantum sensors under a reference lamp. The reference quantum sensors are recalibrated with a 200 W
quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST).
