Application Summary AI generated
GB/T 35139-2017 specifies the technical requirements, test methods, and calibration procedures for photosynthetic active radiometers, which measure photosynthetically active radiation (PAR) in the 400–700 nm wavelength range. It is primarily applied in agricultural meteorology, plant physiology research, and greenhouse environmental monitoring to quantify light available for photosynthesis. The standard ensures accuracy and consistency of PAR measurements used in crop growth modeling, solar energy assessment, and ecological studies.
