WSD-3C Type Fully Automatic Whiteness MeterDetailed product description：

Features of WSD-3C fully automatic whiteness meter:

Full Chinese display: Chinese prompts can be provided for various operations, making it easy to use.
Wide application range: The instrument can perform reflective measurements on surfaces such as solid samples, powder samples, paste samples, and silk samples.
Excellent measurement performance: Using computer-aided design, the spectral characteristics of the instrument measurement sensor fully comply with the CIE standard observer response curve, and can accurately obtain XYZ tristimulus values.
Rich color system and chromaticity values: The instrument provides multiple color systems, whiteness values, and reference color differences.
Good stability and reproducibility: The instrument adopts Kangguang's patented technology, eliminating the vast majority of system drift errors.
High automation and multifunctionality: The instrument can automatically collect and process data during operation, with simple and fast operation. The instrument also has complete editing functions, and users can input or modify the data and color difference target values of the standard whiteboard through the keyboard, and can freely choose the output mode.
The instrument has an RS-232 communication interface, which can output measurement data to a computer or a printer.
