The Spectrophotometer PCE-CSM 5 was developed for quality control and offers a high accuracy. When using the Spectrophotometer, you can choose between different color spaces (CIE LAB, XYZ, LCh, RGB, LUV). In addition, the Spectrophotometer PCE-CSM 5 comes with two different measuring apertures (Ø4 mm and Ø8 mm). After a measurement with the Spectrophotometer, the reading can be used as a reference value while other readings can be recorded as a sample and later be compared to the reference value easily.
