This professional instrument combines illuminance measurement and solar photosynthetically active irradiation intensity measurement in one compact device. Designed for accurate readings in various lighting conditions, particularly with LED light sources, it measures irradiation intensity in the effective wavelength range (400-700nm) crucial for green plant photosynthesis. Ideal for greenhouse cultivation, plant factories, indoor botanical facilities, and scientific plant research.
Note: Reading error may increase under incandescent lamps or monochromatic yellow light sources.
