Description

Quantum Pyranometer – Measures Photosynthetically Active Radiation (PAR)in the 400 to 700 NM waveband.


Feature

Used by agriculturists, botanists, horticulturists, ecologists, and environmental scientists to measure PPFD (Photosynthetic Photon Flux Density) in the atmosphere, growth chamber, and greenhouse

  • Accurate measurements under natural and arti?cial light conditions
  • Colored glass ?lters are used to tailor the response to the desired waveband using an interference ?lter to provide a sharp cutoff at 700 nm which prevents any infrared light from being measured.
