Overview

Fluorescence whiteness meter/whiteness meter is mainly suitable for measuring the whiteness of objects or powders with flat non colored surfaces, and can accurately obtain whiteness values consistent with visual acuity. For objects treated with fluorescent whitening agents, the whiteness value after fluorescence enhancement can be quantitatively reflected.

Product Details

WSB-VI-YFluorescence whiteness meter/whiteness meterIt is mainly suitable for measuring the whiteness of objects or powders with flat non colored surfaces, and can accurately obtain whiteness values consistent with visual sensitivity. For objects treated with fluorescent whitening agents,Can quantitatively reflect the whiteness value after fluorescence enhancementIt can be widely used for measuring the whiteness of substances such as textile printing and dyeing, paint and coatings, chemical building materials, paper and cardboard, plastic products, ceramics, enamel, talcum powder, starch, flour, salt, detergents, cosmetics, etc. This instrumentThe overall whiteness is composed of a light source, optical system, detection system, data processing and display system, etcR457.R457=Blue light whitenessr457+Fluorescent whitening degreeF.The spectral diffuse reflectance shooting ratio is defined as1The ideal surface whiteness is100The whiteness of a black surface with zero diffuse reflectance is0.This instrument is designed according to the lighting committee（CIE）Designed according to specified standard light sources and lighting conditions, rigorously tested and debugged, and implemented in accordance with enterprise standardsQ/TDKY02-2004, applicable toGB2913、GB5950、GB8940.1、GB12097、GB13025.2Waiting for national standards.
