DRK103 Whiteness Color Meter

Products Details

  DRK103 whiteness color meter is also called colorimeter, whiteness colorimeter, whiteness color meter, etc. It can be widely used in papermaking, printing, ceramics, chemical, textile printing and dyeing, building materials, food, salt and other industries to determine The whiteness, yellowness, color and chromatic aberration of the object. Features The instrument adopts optical, mechanical, electrical integration and microcomputer measurement and control technology, has the function of statistical processing of test data, can be printed out, and can measure the whiteness (brightness) and chromaticity of various objects. 1. Measure the color of the object, report the diffuse reflection factors RX, RY, Rz, stimulus values ​​X10, Y10, Z10, chromaticity coordinates X10, Y10, lightness L*, chromaticity a*, b*, chromaticity C*ab, Hue angle h*ab, dominant wavelength λd, excitement purity Pe, color difference ΔE*ab, lightness difference ΔL*, chroma difference ΔC*ab, hue difference ΔH*ab, Hunter system L, a, b; 2. Determine the yellowness YI; 3. Determine the opacity OP; 4. Determine the light scattering coefficient S; 5. Determine the light absorption coefficient A; 6. Measure transparency; 7. Determine the ink absorption value; 8. The reference sample can be in kind or data. The instrument can store and memorize the information of up to ten reference samples; 9. Multiple measurements can be averaged; digital display and printable report measurement results; 10. The instrument has a memory function. Even if the power is turned off for a long time, useful information such as the zero adjustment, calibration, standard sample and reference sample value of the memory will not be lost. Applications 1. Measure the color and chromatic aberration reflected by the object; 2. Measure ISO brightness (blue whiteness R457) and the fluorescent whitening degree of fluorescent whitening materials; 3. Measure CIE whiteness (Gantz whiteness W10 and color cast value TW10); 4. Measure the whiteness of building materials and non-metallic mineral products; 5. Measure yellowness; 6. Measure the opacity, transparency, light scattering coefficient and light absorption coefficient of the sample; 7. Measure the ink absorption value. Technical Standard GB 7973: Pulp.
