Handheld plant spectrometer

Handheld plant spectrometerPG200N is a device that can quickly measure light intensity, light quality, and spectrum. With just one click, it can capture the intensity and composition of five wavelength bands of light: near ultraviolet (350-400nm), blue light (400-500nm), green light (500-600nm), red light (600-700nm), and far red light (700-800nm) with an accuracy level of 1 nm. This device is a widely recognized portable spectral measurement device internationally, and related research results have been published in multiple top journals. It can be used to optimize the wavelength composition of artificial fill light, track spectral data of lighting equipment for a long time, verify the effectiveness of light sources and fill light schemes, etc. The application scope of this device covers facilities horticulture and plant factories, plant physiology research, agricultural cultivation and breeding research, forestry, ecology and other fields.

Handheld plant spectrometerEquipped with high-precision CMOS linear optical sensors, it can capture photon flux density (PFD) in increments of 1 nm (12nm bandwidth) between 350-800nm, and the sensor measures with accurate cosine correction response to ensure the accuracy of the entire field of view.
