PUSHEN WSB digital Whiteness Instrument

WSB

Digital Whiteness Instrument

Used to test the whiteness value of paper, Spinning & weaving, plastic, paints, etc., using 30W halogen tungsten lamp, WSB digital Whiteness Meter indication interval is 0-100, error of indication is +/- 2.5.

Introduction

The WSB digital display Whiteness Meter is composed of a light source, an optical filter, a sample holder and a photoelectric Detector as a whole, and the overall whiteness value is blue light whiteness R457.

Define the whiteness of a satisfactory surface whose spectral diffuse reflectance is 100% as 100 degrees, and the whiteness of an absolute black surface whose spectral diffuse reflectance is zero is zero degree.

The instrument is designed in full accordance with the standard light source A and the lighting conditions 45/0 stipulated by the International Commission on Illumination (CIE). After strict testing and debugging, the instrument complies with JJG512-2002 national metrology verification regulations, and is implemented in GB2913, GB5950, and GB8940. 1. GB12097, GB13025.2 and other national standards.

Applications

WSB digital display Whiteness Meter is mainly suitable for measuring the whiteness of non-color flat objects or powders. The whiteness value consistent with the visual sensitivity can be accurately obtained. For objects treated with fluorescent whitening agents, it can quantitatively reflect the whiteness value after fluorescent whitening. For paper opacity can be accurately measured.

This instrument can be widely used in the whiteness measurement of textile printing and dyeing, paint coating, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, china clay, talcum powder, starch, flour, salt, detergent, cosmetics and so on.
