Product Details
Application:
Brightness Tester is a specialized printing test machine for the brightness, transparency, fluorescence of toilet paper, paper, paperboard, adhesive sticker and surface of carton. This tester could be used to test the transparency, opacity, Light scattering coefficient and absorption coefficient of paper. It could also be used to test the brightness and fluorescence whiteness of coating, ore powder, flour, salt, milk powder, ceramic, textile and other materials.
Function:
1.Test ISO Brightness (the R457 brightness) Fluorescent whitening transmitted by fluorescent substance from samples of fluorescent brightness.
2.Test brightness stimulus Y10, opacity, light scattering coefficient and absorption coefficient.
