RY-GH Photosynthetic Active Radiation Par Sensor For Greenhouse Price

The photosynthetically effective radiation sensor is mainly used to measure the photosynthetically effective radiation of natural light in the wavelength range of 400-700nm, and is simple to use. It can be directly connected to a digital voltmeter or a data collector and can be used under all weather conditions. The meter uses a silicon photodetector and passes through a 400-700nm optical filter. When there is light, a voltage signal is generated that is proportional to the intensity of the incident radiation, and its sensitivity is proportional to the cosine of the direct angle of the incident light. μ • mol / m2 • s. This table is widely used in agricultural meteorology and crop growth research.
