PARTS LIST (What’s in the Box)
The PHOTOBIO by Phantom Quantum PAR meter is designed to measure PAR
(Photosynthetically Active Radiation) ux 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.
