    PCE Instruments CSM 4 Colorimeter Ø20 mm Aperture

    # CSM 4

    • Automatic calibration of black-and-white contrast
    • Continuous performance
    • Designed for the food industry
    • Measures various colors
    • Application on different surfaces
    • 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 that 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 is applied especially in industries where the characteristics of colors play a big role. Whether it is dental technology, painting industries, or the production of plastic bags, the colorimeter PCE-CSM 4 is an ideal product for quality management and thus assures the highest reliability, whenever it is important to assure a certain standard in optic quality.
    • The colorimeter supports an ergonomic design and features user-friendly menu navigation. The colorimeter PCE-CSM 4 has a large measuring aperture of 20 mm. 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 analyze, 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.
