Spectrometer Compact MK350D

The MK350D is the world smallest stand-alone light measurement device, no computer needed, records over 27 light units (CCT, RA, CIE1976 CIE1931, LUX, FC, LamdaP, R9 et al) plus, Flicker is measured by one click,this new feature could be very interesting for lighting designers and lighting advisors, It is also a wireless controllable system that allows users more possibilities to manage their testing. Pocket-sized portability, a Free powerful spectrum software-uSpectrum included.
