Outstanding Features

• Integrated dual light source (LED + UV): This is the most valuable feature of the DS-220. The addition of an ultraviolet (UV) light source allows the device to extremely accurately evaluate samples containing optical brightening agents (OBA). This feature is a must-have when you need to inspect the color of white paper, textiles, leather shoes, or detergents.
• Three flexibly switchable measurement apertures: The device is equipped with 3 measurement apertures including Φ11mm, Φ6mm, and Φ3mm. This diversity helps users handle all types of sample sizes: from wide flat surfaces (using 11mm) to medium details (using 6mm), and especially ultra-small components and curved surfaces (using 3mm) with just a single device.
• D/8 optical system, SCI: Similar to industry-standard models, the DS-220 uses a diffuse illumination structure, an 8-degree viewing angle, and measures in SCI (Specular Component Included) mode. This mode collects all reflected light, helping to analyze the true color of the material without being deceived by surface gloss or roughness.
• High accuracy and repeatability: The device provides a very detailed display resolution (0.01) and excellent repeatability at dE*ab ≤ 0.03. This ensures that measurement results are always consistent, helping to detect even the smallest color deviations between batches.
• Intuitive operation, fast processing: With a crisp color screen and user-friendly interface, users can easily read Lab*, dE*ab indices, and receive Pass/Fail alert results instantly, optimizing the workflow speed at the production workshop.

Practical Applications

Thanks to the flexibility of 3 apertures and the UV light source, the CHN SPEC DS-220 is a comprehensive QC solution for:

• Textile, footwear, and paper industry: Accurately measure fabrics, paper, and cardboard containing optical brighteners thanks to the UV light source.
• Plastics and electronic components industry: Color measurement on small plastic parts, phone components, and household appliances (using 3mm and 6mm apertures).
• Paints and coatings industry: Evaluate color deviation of industrial paints and electrostatic powder coatings on flat and curved surfaces.
• Printing and packaging: Quickly inspect the color of packaging and labels during mass production.
