The Colorimeter proves to be a good multitasking device. It is designed to measure the color spectrum of various objects. Light consists of a broad spectrum of colors which are not always purely white, black or blue. A light-source illuminates an object, which then absorbs part of that light and reflects another one. That reflected light can be then detected by a sensor in order to determine the reflected wavelengths and thus calculate its color. Colorimeters are often applied in areas of quality control in industrial sectors. Colorimeter of the PCE-CSM series are applied especially in industries where the characteristics of colors play a big role. Whether it is dental technology, painting industries or for the production of plastic bags, the colorimeter PCE-CSM 4 is an ideal product for quality management and thus assure highest reliability, whenever it is important to assure a certain standard in optic quality.
