Be confident in your purchase, we're an Authorized PCE Instruments Dealer. Highlights: Great for quality control PC software included Li-ion battery Different color spaces Determination of reference values and samples White calibration The PCE CSM 3 Color Meter was developed for quality control and offers a high accuracy. You can choose between different color spaces (CIE L*a*b*C*h, CIE L*a*b*). After a measurement with the device, 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. In addition to the individual color space coordinates, the deviation between the reading is also displayed. When using the color meter, it is possible to store up to 100 reference values and up to 20,000 samples on the device. The measured data can also be transferred to a PC via the USB interface. A special PC software is included in the package.
