The Best PAR Meters
RY-GH photosynthetically active radiation sensor is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400-700nm. It can be directly connected with digital voltmeter or data collector, 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, a voltage signal proportional to the intensity of the incident radiation is generated, and its sensitivity is proportional to the cosine of the direct angle of the incident light. Each par meter gives its own sensitivity (when the original millivolt voltage is output), which can directly calculate the value of μ· mol / m2 · s.
