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).
