PNSHAR PN-48A whiteness Color Tester ISO whiteness chroma Lab value color difference yellowness etc

PN-48A whiteness color Tester is widely used in papermaking, printing, textile printing and dyeing, ceramic enamel, building materials, chemical industry, grain, salt and other industries, used to determine the whiteness, yellowness, color and color difference of objects, and determine the (in)transparency, light scattering coefficient, light absorption coefficient and ink absorption value of paper.

Features

1. Measure ISO whiteness (ISOBrightness, that is, R457 whiteness), and the fluorescence whiteness produced by the reflection of fluorescent substances can also be measured for the fluorescent whitening sample.

2. Measure the brightness stimulation value Y10;

3. Determination of opacity and determination of transparency;

4. Determination of light scattering coefficient and absorption coefficient;

5. It can be measured multiple times and give the arithmetic mean of a series of measurement results;

6. With power-off protection function, data such as zeroing, alignment and standard value will not be lost even under the condition of long-term power loss;

7. Simulate D65 illuminator lighting. The CIE1964 supplemental chromaticity system and the CIE1976 (L*a*b*) color space chromatic aberration formula were used.
