PAR200 Quantum Spectrometer

Measure PPFD and PPF

The light visible to the human eye (approx. 380-780 nm) is also used by plants. This part of the electromagnetic radiation, which powers photosynthesis, is named PAR and is usually found in
wavelengths from 400 to 700nm.
For plant growers, biologists, and scientists the most important data in the light requirements for plants is PPFD (photosynthetic photon flux density). PPFD is a measurement of the amount of light
that reaches a plant (the number of photosynthetically active photons that fall on a given surface each second).
However, for growing light manufacturers, PPF and PFD measurement will be also important. This evaluates the total amount of energy that is produced by a light source per second.
The ideal tool for measurements of light that stimulates plant growth is our PAR200 Quantum Spectrometer which works in the PAR spectra and expresses PPFD values in μmol/m2/s and PPF
in μmol/s. Also for the laboratory applications we specially designed the PAR200 enriched with a high resolution and extended spectral range. To be able to analyze, compare, and report all the data it is highly recommended to use our uSpectrum laboratory-grade PC software compatible with the PAR200 spectrometer.
