Spectrometer Advanced MK350S

When using artificial lighting, uniformity and constant quality of the light spectrum is very important for a constant quality of crop production. Set your light to spread out under certain conditions to increase lighting quality. It is an economical and reliable measurement solution that can be real-time and in sit monitoring light quality and solve business and specification controversy. Records over 37 light unit-of-measures; Basic List items (PPF, CCT, CRI, CQS, CIE1976 , CIE1931, LUX, FC, LambdaP, R1 to R15, S/P ratio); additional free uSPECTRUM PC software and iOS/Adroid APP for quickly sharing product information for multiple purposes in lighting, horticulture and photography industry.
