WSB-3 Whiteness meterDetailed product description：

Usage Overview
It 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, the whiteness value after fluorescence enhancement can be quantitatively reflected. The opacity of paper can be accurately measured. It 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, white cement, ceramics, enamel, talcum powder, starch, flour, salt, detergents, cosmetics, etc.

Product Features
Microcomputer, touch keyboard, LCD backlit display screen, standard serial RS232 data communication interface
Nonlinear data processing and data smoothing function, fast automatic multi-point correction, self diagnostic information prompt, fast and stable response, maintenance free and reliable operation
Excellent color measurement performance, extremely accurate. Using computer-aided design, the overall spectral characteristics of the instrument fully comply with the CIE standard observer response curve, and can accurately obtain ISO whiteness
By using a modified color filter system, the whiteness value after fluorescent whitening can be quantitatively reflected, limited to WSB-2A. With simple operation, the opacity of the paper can be accurately measured
High stability and reproducibility, completely eliminating system drift errors, equipped with data storage and query functions, can meet GLP requirements
Equipped with imported original components, high-efficiency and low loss switching power supply, reasonable and concise optical path design, and good reliability,
