Colorimeter CSM 3 for quality control
PC software included / Li-ion battery / different colour spaces / 
determination of reference values and samples / white calibration


The colorimeter CSM 3 was developed for quality control and offers a high accuracy. When using the colorimeter, you can choose between different colour spaces (CIE L*a*b*C*h, CIE L*a*b*). After a measurement with the colorimeter, 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 colour space coordinates, the deviation between the reading is also displayed. When using the colorimeter, 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.
