PAR 2000

Measuring the photon flux density

The PAR 2000 measures the photosynthetically active radiation (PAR) in the wavelength range between 400 – 700 nm. It is mainly in this range that incoming radiation is used by most plants for photosynthesis and thus for producing energy. The measurement is performed by determining the photon flux density, which describes the quantity of incoming light quanta per area and time. The PAR 2000 can be used for measurements under artificial light sources, global sunlight and a mix of different radiation sources. It is suitable for professional usage, both outdoors and indoors.
