Brightness Tester

This tester is used to measure the brightness(ISO Brightness, R457 whiteness), fluorescent whitening degree, the transparency, opacity, light scattering coefficient and absorption coefficient of paper  the object, it is widely used in papermaking, textile, printing, plastics, ceramics, enamel, food, building materials, paints, chemicals, salts and other special need to measure the whiteness body production and inspection department.

1. Adopt new module circuit design with WIFI Internet of Things function. After networking the test results can be saved to the cloud server and through the dedicated PN-QMS series quality management system data query management big data analysis and statistics and visual large-screen display can be performed;
2. It has the function of column chart display which is convenient for checking the test results;
3. Determination of transparency and opacity;
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 the data such as zero adjustment calibration and standard value will not be lost even if the power is off;
7. Simulate D65 lighting. The geometry was observed with d/0 illumination.
