The Phantom PHOTOBIO Advanced Quantum PAR Meter provides accurate and cost-effective measurement for any light source used in horticultural applications.  The Advanced Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a positive proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis, important for maximizing crop yield.  

Complete with compact main unit, remote sensor, two connection cables (short-coiled & 12’ long-straight), AAA batteries and protective carrying case.  Convenience of storing up to 99 measurements for easy reference while adjusting light fixture height, dimmer setting and other environmental changes throughout each phase of growth.
