DRICK DRK103 whiteness Color instrument

Introduction

DRK103 whiteness colormeter, also known as Colorimeter, whiteness Colorimeter, whiteness colormeter, etc., can be widely used in papermaking, printing, ceramics, chemical, textile printing and dyeing, building materials, grain, salt and other industries, used to determine the whiteness, yellowness, color and color difference of objects.

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, and can measure the whiteness (brightness) and chromaticity of various objects.

1. Measure the color of the object, report the diffuse reflection factor RX, RY, Rz, stimulus value X10, Y10, Z10, color coordinates X10, Y10, brightness L*, chromaticity a*, b*, chroma C*ab, hue angle h*ab, main wavelength λd, excitatory purity Pe, chromatic aberration ΔE*ab, brightness difference ΔL*, chromaticity difference ΔC*ab, hue difference ΔH*ab, Hunter system L, a, b;

2. Determination of yellowness YI;

3. Determine opacity OP;

4. Measure the light scattering coefficient S;

5. Measure the light absorption coefficient A;

6. Measure transparency;

7. Determine the ink absorption value;

8. The reference sample can be a physical object or a data. The instrument can store and memorize up to 10 reference sample information;

9. The average value can be taken for multiple measurements, and the measurement results can be printed and reported digitally;

10. The instrument has a memory function. Even if the power is lost for a long time, useful information such as zeroing, calibration, and the magnitude of standards and reference samples will not be lost.

Applications

1. Measure the color and color difference reflected by the object;

2. Measure ISO brightness (blue light whiteness R457) and fluorescence whitening 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.
