Photosynthetically active radiometer

Photosynthetically active radiometer is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400-700nm. It is easy to use and can be directly connected to a digital voltmeter or data logger and can be used in all-weather conditions.

The sensor uses a silicon photodetector and passes through a 400-700nm optical filter. When there is light, it generates a voltage signal proportional to the incident radiation intensity, and its sensitivity is proportional to the cosine of the direct angle of the incident light. Each Photosynthetically active radiometer gives its own sensitivity (when the original millivolt voltage is output), which can directly calculate the value in units of μ•mol/m2•s.

FT-FS3 Photosynthetically active radiometer is widely used in agricultural meteorology and crop growth research.
