Quantum Meter

Quantum meters approximate the quantity of photons between 400 and 700 nanometers. Photosynthesis is largely driven by the number of photons between these wavelengths so this radiation is called the Photosynthetic Photon Flux (PPF) and is measured in µmol m-2 s-1 (micromoles of photons per meters squared per second). This meter includes data recording capability and sun and electric calibration with each meter. The instrument 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 communication cable (AG52-304) must be purchased to download data to a PC. These meters feature an innovative blue lens for improved spectral response along with a cosine-corrected head, self-cleaning characteristics, and long-term stability.
