Quantum Meters measure instantaneous Photosynthetic Photon Flux (PPF) in µmol m-2 s-1.
 
Our meters now include data recording capability and sun and electric calibration with each meter.
Each meter can store up to 99 manually recorded measurements. In automatic mode, measurements are made every 30 seconds and averages are stored every 30 minutes. Daily totals are also calculated and the past 99 days are recorded. The AC-100 communication cable must be purchased to download data to a PC.

These meters still feature our innovative blue lens for improved spectral response along with our cosine-corrected head, self-cleaning characteristics, and long-term stability.
