YQ-Z-48A whiteness color meter Introduction: Whiteness color measuring instrument is also called: whiteness color meter, colorimeter, color difference meter, color measuring instrument, color measuring instrument, whiteness colorimeter, comparative color measuring instrument, color difference measuring instrument, color analyzer, color measuring instrument . Widely used in paper, printing, ceramics, chemical, textile printing and dyeing, building materials, food, salt and other industries, used to determine the object's whiteness, yellowness, color and color difference, can also determine paper opacity, transparency, light scattering Coefficient, light absorption coefficient and ink absorption value. The main functions are as follows: Measuring object chromaticity, chromatic aberration, Hunter system value Lab; Measuring object ISO whiteness (blue light whiteness R457) and Z whiteness (Rz), fluorescent whitening F of fluorescent whitening material; Measuring CIE whiteness (Ganz whiteness W10 and color cast value Tw10); Measuring ceramic whiteness, Hunter whiteness WH; Measuring the whiteness of building materials and the whiteness of non-metallic mineral products WJ; Measuring yellowness YI; Measuring transparency T, opacity OP, light scattering index, and light absorption index; The ink absorption value was measured. Features: 1. Determine the color of the object, report the diffuse reflection factor RX, RY, Rz, the stimulus value X10, Y10, Z10, the chromaticity coordinates X10, Y10, the brightness L*, the chromaticity a*, b*, the chroma C*ab, Hue angle h*ab, dominant wavelength λd, excitation purity Pe, color difference ΔE*ab, brightness difference ΔL*, chroma difference ΔC*ab, hue difference ΔH*ab, Hunter system L, a, b; 2. Determination of yellowness YI; 3. Determine the opacity OP; 4, measuring the light scattering coefficient S; 5. Measuring the light absorption coefficient A; 6. Measuring transparency; 7. Determine the ink absorption value; 8, the reference can be physical, but also data. The instrument can store up to ten reference samples of memory; 9, multiple measurements can take the average; digital display and can print the report measurement results; 10. The instrument has a memory function. Even if the power is turned off for a long time, the useful information such as zero adjustment of the memory, calibration, standard sample and reference sample will not be lost. Technical Parameters: 1. Simulate D65 light source illumination. CIE 1964 supplementary color system and CIE1976 (L*a*b) color space color difference formula; 2. Observe the geometric conditions using d/o illumination. The diffusing ball has a diameter of 150mm and a test hole diameter of 25mm. It is provided with a light absorber to eliminate the influence of the specular reflected light of the sample; 3. Measurement repeatability: δ(Y10)<0.1, δ(x10, y10)<0.001; 4. Accuracy: △Y10<1.0; 5, sample size: test plane ≥ ¢ 30mm, thickness ≤ 40mm; 6, power: 220V ± 10%, 50Hz; 7, working environment: temperature 10 ~ 30 ° C, relative humidity does not exceed 85%; 8. Dimensions (length × width × height), mm: 370 × 270 × 410; 9, instrument quality: about 15kg.
