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.
