Product Info

TD20S4005 is a Photosynthetically active pyranometer, also known as light quantum number, is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400~700nm. The meter uses a silicon photodetector and passes through an optical filter from 400 to 700 nm. When there is light irradiation, a voltage signal proportional to the intensity of incident radiation is generated, and its sensitivity is proportional to the cosine of the direct angle of the incident light. Each photosynthetically active pyranometer gives its own sensitivity and can be read directly. The unit is μmol/m2·s. This table is widely used in agricultural meteorology, crop growth research.
