The Material Tester enables precise and objective color measurement and reliable determination of color deviations. Our Material Tester measures color values in the Lab, XYZ, xyY and R s/G s/B s color spaces and also displays important color indices such as whiteness (WI), yellowing index (YI) and color temperature (Tw). The integrated ΔEab calculation allows the color difference to be determined directly. An adjustable tolerance function (PASS/WARN/FAIL) immediately indicates whether the measured color is within the specified limits. The device measures directly on the sample, can store multiple measurements and target values, and covers a brightness range of 5 to 100. Power is supplied by three AA batteries, making the Material Tester particularly mobile and flexible – ideal for measurements directly on site. Thanks to its versatile applications, the device is ideal for quality control in the production of textiles, paints, plastics, leather or paper, as well as for laboratories and color testing. By displaying different color spaces and automatically calculating color differences, it helps users to evaluate colors objectively and comprehensibly. The Material Tester delivers precise and reproducible results without the need for visual assessments, making it an indispensable tool for standardized color analysis and professional color control.
