Veinasa-GH Aluminum Alloy Sun Photosynthetically Active Radiation PAR Sensor Modbus Solar Iradiation Meter

Photosynthetically active radiation meter, also called quantum number, is used to measure photo-synthetically active radiation of natural light in the wavelength range of 400 to 700nm. It can be connected directly to a digital voltmeter or data logger.
The meter uses a silicon photo-detector and passes a 400-700nm optical filter. When illuminated by 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 photosynthetic active radiation meter gives its own sensitivity and can be read directly.
