Testermeter- SKZ102A Brightness Meter Testing Equipment for Plastic Opacity Meter Machine
| 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 |
Function:
| 1. Test R457 or ISO Brightness 2. Analysis if it contains fluorescent whitening agent and determination of reflection fluorescence produced by white fluorescent, that is, degree of whitening 3. Test the brightness value of Y10, Ie, the green light diffuse reflectance factor Ry. 4. Test non-transparency, transparency, light scattering and light absorption coefficient 5. Test the ink absorption value of paper and board. |
Feature
| 1. Using d/o lighting observation geometry (ISO2469), diffuse spherical diameter φ150mm, with a light absorber, eliminating the specular reflection of the sample. 2. Spectral power distribution of R457 whiteness optical system peak wavelength 457nm, full width at half maximum 44nm 3. RY optical system in line with GB3979-83: object color measurement methods. 4. Can be measured multiple times and give the average of the results. 5. With power protection, zero, adjustment and standard values and other data, even if the long-term power loss, the data will not be lost. 6. Using LCD display, using a menu-style user interface, easy to operate. 7. Determination and digital display whiteness, fluorescence (whitening) brightness, opacity (%) 8. Using thermal micro printer, print the required data, the noise is minimal. |
Standards:
| ISO2470: paper and board Blu-ray diffuse reflectance factor method (ISO brightness); ISO2471: paper and cardboard is not transparent method; ISO2469: d/o lighting observing geometry terms |
