Apogee MQ-500 PAR PPFD Quantum Meter | 0-4000 micromol/m2/s, plus or minus 5% Microbial & Biostimulants 5 in Sidewall Height 6Apogee MQ 500 PAR PPFD Quantum Meter for Lab Grade PPFD Readings The Apogee MQ 500 is the meter most commercial growers reach for when canopy maps need to hold up to a state inspector. A blue enhanced silicon photodiode plus a custom optical filter holds calibration uncertainty within plus or minus 5% across the 400 700 nm PAR band. Measurement runs to 4,000 micromol m2 s past the saturation point of any LED or HPS in production. Long term drift is
