Precision PAR Measurement for Optimal Plant Growth

Precision PAR Measurement for Optimal Plant Growth

Photosynthetically active pyranometer is an instrument used to measure the radiant energy in a certain band (wavelength is 400nm~700nm) in the solar radiation spectrum that can be absorbed and converted by plastid pigments of green plants and used to synthesize organic substances. It is designed in strict accordance with the "GB/T35139-2017" national standard. It consists of sensing devices, filters, cosine correctors, signal output terminals and structural components.
