Nr4520 Whiteness Meter Brightness Tester Reflectance Test
NR4520 Whiteness Meter
This model NR4520 whiteness meter is used to determine the ISO R457 whiteness, CIE whiteness,ASTM E313 whiteness, yellowness Yl, reflectance of objects, and it is widely used in paper making, textile,printing and dyeing, plastics, ceramics, enamel, food, building materials, paint, chemicals, salt and other production and commodity inspection departments that need to measure the special body whiteness. The production and commodity inspection department. It is also suitable for measuring various specular reflectivity values.
Features:
Measure lSO Brightness (IS0 Brightness, that is,R457 whiteness), for fluorescent whitening samples, you can also measure the fluorescent whitening caused by the reflection of fluorescent substances.
1. In addition to lSOR457 whiteness, it can also measure CIE whiteness,ASTME313 whiteness, yellowness Y l,reflectance;
2. It can measure multiple times and give the arithmetic average of a series of measurement results;
3. Simulate D65 illumination light source,45/0 (45 degree illumination, 0 degree reception), in line with standard CIE No.15,GB/T 3978.
