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 for horticultural studies and
monitoring plant physiology.
