GELAIMO WSB digital Whiteness Meter Whiteness Detector

Introduction

The WSB digital Whiteness Meter is composed of a light source, a filter, a sample holder and a photoDetector, and the overall whiteness value is blue light whiteness R457. Define the whiteness of a satisfactory surface with 100% spectral diffuse reflectance as 100 degrees, and the whiteness of an absolute black surface with zero spectral diffuse reflectance as 0 degrees. This instrument is designed in full accordance with the standard light source A and illumination conditions 45/0 stipulated by the International Illumination Commission (CIE), through strict testing and debugging, the instrument conforms to JJG512-2002 national metrology verification regulations, and implements GB2913, GB5950, GB8940.1, GB12097, GB13025.2 and other national standards.

Features

★ CAD computer-aided design is used to make the shape of the instrument more reasonable and better.
    ★ Effective, low-loss switching power supplies are used for higher reliability.
    ★ Good imported components are used to make the work more stable and the service life longer.
    ★ The simple optical path design is adopted, which is easier to use and maintain.
    ★ With a modified color filtering system, the whiteness value after fluorescence whitening can be quantitatively reflected.
    ★ The reasonable design of the specimen holder and movable platform can effectively avoid the light leakage of the measuring orifice.
    ★ With a simple operation, the opacity of the paper can be accurately measured.
    ★ The national calibration whiteboard is used to transmit the correction value to make the measured value more accurate.
