INSTRUCTION MANUAL
The Quantum Par Meter is designed to measure PAR (Photosynthetically Active
Radiation) flux in wavelengths ranging from 400 to 700 nm. There is a proportional
relationship between the number of photons absorbed in 400 to 700 nm band and
the rate of photosynthesis in plants, which is important for horticultural studies
and monitoring plant physiology. This compact, fully portable handheld light meter
measures up to 10,000 in units of micro-mol per meter squared per second (umol/
m2/s) which is also called Photosynthetic Photon Flux Density (PPFD).
