The Colorimeter proves to be a true multitasking device. It is designed to measure the color spectrum of various objects. Light consists of a broad spectrum of colours 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 colour. Colorimeters are often applied in areas of quality control in industrial sectors. Colorimeter of the CSM series are applied especially in industries where the characteristics of colours play a big role. Whether it is dental technology, painting industries or for the production of plastic bags, the colorimeter CSM 2 and CSM 4 are ideal products for quality management and thus assure highest reliability, whenever it is important to assure a certain standard in optic quality. 

The colorimeter supports an ergonomic design and features a user-friendly menu navigation. The difference between the colorimeter CSM 2 and CSM 4 is the size of the aperature. The colorimeter CSM 2 has a size of 11 mm, while the colorimeter CSM 4 has a larger measuring aperture of 20 mm. Due to this design difference, the devices are ideal for individualised applications in various divisions. The supported color spaces of the colorimeter  CSM 2 and CSM 4 are CIEL*a*b*C*h, CIEL a*b*, and CIEXYZ. Thus the colorimeter is designed for application in professional industries. Another advantage of the colorimeter of the PCE-CSM series is that it supports a vertical justification. This means that the whole device does not need to be placed on the object to analyse, but only the part with the sensor in it. The industrial perspective of it is that this method allows the measuring of damp objects, textiles and even food. The colorimeter CSM 2 and CSM 4 are therefore ideally applied for measurements of e.g. meat, bananas or tomatoes. Due to the software "CQCS3" that is included in the delivery, the measured data can be read out on a computer or laptop for a digital overview.
