WSS-27 photosynthetically active radiation sensor is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400-700nm. WSS-27 use precision optical detectors and has an optical filter of 400-700nm, when natural light is irradiated, a voltage signal proportional to the intensity of the incident radiation is generated, and its luminous flux density is proportional to the cosine of the direct angle of the incident light.

MARCOM will be closed for the summer between 12/08 and 19/08 inclusive. Orders can still be sent and will be handled in order of arrival.
