PHOTOBIO Advanced Quantum PAR Meter Water Pumps & Irrigation Supplies Rich Humic lab results showAll new for 2020, the Advanced Quantum PAR Meter provides accurate and cost effective measurement for all light sources used to grow plants. The PHOTOBIO by Phantom Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis in plants, which is important
