Advanced Quantum PAR Meter
OVERVIEW
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.
IMPORTANT: To ensure safety, please read this manual carefully before
installation and follow the instructions herein. Store this manual in a secure
place for future reference.
