Product Highlights

• Integrated Color & Gloss Measurement (2-in-1): With just a single click, the device simultaneously provides optical color data and surface gloss values of the material, saving time and equipment investment costs.
• Intelligent Auto-Calibration System: The device automatically recognizes and calibrates when placed into the calibration base (White/Black calibration) based on environmental factors, without complex manual operations. It integrates a BCRA green tile for wavelength accuracy self-calibration.
• Sample Positioning with Built-in Camera: Allows users to clearly see the actual area to be measured on the screen, preventing off-center placement or incorrect positioning on samples with complex patterns or ultra-small dimensions.
• NetProf Network Technology Support: Enables remote calibration and device synchronization via the internet, minimizing parameter drifts caused by component wear and tear over time.

Practical Industrial Applications

Thanks to its wide wavelength range from 360 – 740 nm and first-level metrology qualification hardware accuracy, the DC-26CG is widely applied in:

• Plastics & Rubber Industry: Inspecting the color of plastic pellets, plastic films, and molded products.
• Paints & Coatings Industry: Measuring and color matching for automotive paint and powder coatings, controlling color deviation between production batches.
• Printing & Packaging Industry: Controlling printing ink density, ensuring brand packaging colors strictly match the Pantone color system.
• Textile & Leather Industry: Measuring the color of fabrics, yarns, and tanned leather, especially effective for fabrics using optical brighteners thanks to the built-in UV source.
• Electronics & Home Appliances Industry: Checking color uniformity of device enclosures and assembled plastic/metal components.
