The photosynthetically active pyranometer is an instrument used to measure the radiant energy in a certain band (wavelength 400nm~700nm) of the solar radiation spectrum that can be absorbed, converted and used to synthesize organic substances by the plastid pigments of green plants. It is designed in strict accordance with the "GB/T35139-2017" national standard. It consists of a sensing device, an optical filter, a cosine corrector, a signal output terminal and structural components.
The photosynthetically active pyranometer adopts an aluminum alloy shell structure; it has the characteristics of solid structure, good sealing, long service life, high measurement accuracy, good stability, long transmission distance, and strong ability to resist external interference. It can be widely used in the environment and agriculture. , aquaculture, greenhouses, laboratories and other various occasions that require photosynthetically active radiation measurement.
