The MK350S Advanced Spectrometer by UPRtek provides accurate light spectrum data quickly within a customizable, user friendly interface. The MK350S allows you to better understand your Agriculture/Horticulture lighting. The PPFD/PAR display screen gives you a quick understanding of your (PPF full spectrum 400-700nm), (PPF-R Red 600-699nm), (PPF-B Blue 400-499), (PPF-G Green 500-599), (PPF-NIR near infer-red 700-780) and (PPF-UV ultraviolet 380-400). The MK350S also measures CCT, Lux, Foot Candles, TM30-15, and Spectrum. One of the unique features of the MK350S is its ability to compare different grow lights and compare the PPFD of both lights. The MK350S is a robust tool that will push your color and brightness management to a new level of accuracy and consistency.



Compare two target LED light fixtures by different segments.
Suitable for QC as tool for counter testing and measureing.
Suitable for Sales as a way of comparing to competing lights.
Suitable for engineering for checking the Lumens and Color of Light fixtures.
