Spectrometer Basic MK350N

The MK350 Spectrometer puts light spectrum data at your fingertips, enabling you to capture in-time readings without the need of a PC. The unit’s advanced sensors measure illuminance, chromaticity, dominant wavelength, and the spectral distribution of all visible light (not Infrared or Ultra Violet). Screen data is rendered as crisp, colorful graphics.
