UPRtek LED Mittari MK350N

MK350N Spectrometer is the first portable LED Meter which can be used without a computer for evaluation of artificial light sources, such as LED, OLED and others. In addition, it can easily measure CCT, CRI, CIE1931/1976 and spectrum distribution and others. It is a Spectrum Analyzer and LED Meter for LED manufacture.

It is great for lighting designers and luminaire industry. Easy and lightweight to carry around as the weight is only 250g.
