MK350N Premium Spectrometer

$2,189.00

The MK350N Premium is a lightweight, portable and easy-to-use spectral illuminance (lux) meter or spectral light meter. It is designed for fast and accurate illuminance measurements for general lighting and LED applications.  Designed to be intuitive and user-friendly, it is ideal for measuring light parameters such as lux, CCT, CRI, CIE Chromaticity Coordinates, Ra, R1 to R15, wavelength and others.  The device also includes an integrated flicker meter.
