Spectrophotometers CM-2500C

Model：CM-2500C
Brand：

The CM-2500c is a 45/0 model spectrophotometer providing  the same accuracy, precision and portability as CM-2500d and CM-2600d of Konica Minolta.
The CM-2500c is best suited for color measurement of samples such as automotive interior parts, coil coatings, plastics, paint, packaging, and raw materials.
The 45/0 viewing optics correlate closely with visual perception of objects.
The innovative optical system ensures perfect annular illumination for best repeatability and stability.
