The Colorimeter proves to be a 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 assures 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 colorimeter PCE-CSM 4 has a large measuring aperture of 20 mm. Due to this alternation the devices are ideal for individualised applications in various divisions. The supported color spaces of the colorimeter PCE-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 PCE-CSM 4 is 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.

The L*a*b color space

Colorimeter NR145 and NR20XE: Color Spaces

Here you can see the color space L*a*b. This color space covers all colors that are visible with the naked eye. L=100 stands for white and L=0 for black. "a+" and "a-" or "b+" and "b-" stands for the color contrasts red, green, yellow and blue.
