color measuring instrument powder PAPER rice digital color meter whiteness meter

Brightness Meter is widely applied in paper and cardboard, pulp, cotton and fabric, plastic, ceramic and porcelain enamel, amylum, construction material, chemical industry, salt making and other testing department that need to test whiteness, yellowness, color and chromatism, as well as transparency, opacity, light scattering coefficient and light absorption coefficient of paper.

Function:

1. Test the color and color difference of reflective objects.

2. Test ISO brightness (Blu-ray brightness R457), as well as the degree of fluorescent whitening of fluorescent whitening materials.

3. Test CIE whiteness (W10 Gantz brightness and color cast value TW10).

4. Test Whiteness of ceramic

5. Test Non-metallic mineral products and construction materials whiteness.

6. Test Measurement System Lab Hunt and Hunt (L*a*b) whiteness.

7. Test yellowness YI

8. Test non-transparency, transparency, light scattering coefficient and light absorption.

9. Test ink absorption value.

Feature

1. Simulation D65 illumination lighting. The CIE 1964 Supplemental Chromaticity System and the CIE 1976 (L * a * b *) color space color difference formula are used.

2 using d / o lighting geometry observation conditions. Diffuse spherical diameter 150mm, test hole diameter 25mm, with a light absorber, eliminating the specular reflection of the sample.

3. Reference samples can be physical, also can be data.

4. Can store up to ten memory samples of reference information

5. Can be measured and given a number of times the average of the results.

6. Digitally display and print report measurement results

7. With memory function. Even if the power is off for a long time, the memory zero, calibration, standard and reference samples will not be lost.

8. LCD display, using the menu-style user interface, easy to operate

9. Determination and display of color, ISO brightness, fluorescence (whitening) whiteness, opacity (%), transparency, light scattering coefficient, ink absorption.

10. The use of thermal micro-printer, you can print the required data, minimal noise.

Standards:

ISO2470: paper and board Blu-ray diffuse reflectance factor method (ISO brightness);

ISO2471: paper and cardboard is not transparent method;
