PNSHAR PN-48B whiteness Tester ISO whiteness fluorescence whiteness transparency

PN-48B

Whiteness Tester

This instrument is used to determine the whiteness of objects, which is widely used in papermaking, textile, printing and dyeing, plastics, ceramics, enamel, grain, building materials, paint, chemical, salt and other production and commodity inspection departments that need to determine the whiteness of special bodies. The instrument can also determine the transparency, opacity, light scattering coefficient and absorption coefficient of the paper.

Features

Measure ISO brightness (i.e., R457 whiteness), and the fluorescence whiteness of the sample can also be measured by the reflection of the fluorescent substance.

1. Determination of the brightness stimulation value Y10;

2. Determination of transparency and opacity;

3. Determine the light scattering coefficient and absorption coefficient;

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

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

6. Simulate D65 illuminator lighting. The geometric conditions were observed by D/O illumination.
