PN-48B Paper Brightness Tester
1. Introduction
Make measurement of ISO brightness (Blue Whiteness R457) and degree of whiteness for Fluorescent whitener.
Make measurement of opacity, transparency, light scattering coefficient and light absorbing coefficient.
Make measurement of ink absorption.
2. Applications
Paper, Board, Pulps,Textile, Plastic, Salt industry, and Industrial powder etc.
3. Features
1. Measure the Blue Reflectance Factor (R457) of samples. Blue Reflectance Factor is so called “Blue Whiteness” or “ISO Brightness”.
