Portable Spectrophotometers CM-2600d / 2500d

A reliable and accurate portable spectrophotometer with sample viewing window for easy sample selection, the CM-2600d and CM-2500d measure color both including and excluding the influence of gloss in one measurement. The instruments are ideal for color measurement of samples with optical brightener such as paper, card and fabrics as they can perform "numerical UV control" which is a unique feature in a portable colour measurement instrument.
