Introduction
NR4520 Whiteness Meter is used to measure the ISOR457 whiteness, CIE whiteness, ASTME313 whiteness, yellowness YIl, reflectivity, it is widely used in papermaking, textile, printing and dyeing, plastics, ceramics, enamel, food, building materials, paint, Chemical, salt and other production and commodity inspection departments that need to measure the whiteness of special bodies. The NR4520 Whiteness Meter is also suitable for measuring various specular reflectance values, measuring ISO brightness (ISO Brightness, that is, R457 whiteness), and for fluorescent whitening samples, it can also measure the fluorescent whitening degree generated by the reflection of fluorescent substances .
Features
1. In addition to ISO R457 whiteness, it can also measure ClE whiteness, ASTM E313 whiteness, yellowness YI, and reflectance;
2. It can be measured multiple times and give the arithmetic mean of a series of measurement results;
3. Simulated D65 illumination body illumination, 45/0 (45 direction incident/0 degree reception), conforming to the standard CIE No.15, GB/T3978.
