Highlights: PC software included Li-ion battery different colour spaces black and white calibration determination of reference values and samples white calibration 3.5" touch screen The PCE CSM 8 Spectrophotometer was developed for quality control, offers a high accuracy, and comes with a 3.5" touch screen display. You can choose between different color spaces (CIE LAB, XYZ, Yxy, LCh, LUV) and 45/0 optics geometry. After a measurement, your 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.In addition to the individual color space coordinates, the deviation between the reading is also displayed. When using the spectrophotometer, it is possible to store up to 1000 reference values and up to 10,000 samples on the device. The measured data can also be transferred to a PC via the USB interface. PC software is included in the package.
