CHN SPEC DS-620 Spectrophotometer (D/8, SCI+SCE, dE*ab≤0.03, Φ8mm/Φ11mm; Φ4mm/Φ6mm; 1*3mm)

CHN SPEC DS-620 Spectrophotometer (D/8, SCI+SCE, dE*ab≤0.03, Φ8mm/Φ11mm; Φ4mm/Φ6mm; 1*3mm)

The CHNSpec DS-620 Handheld Spectrophotometer is a sub-premium version in the DS-600 series, providing a flexible color measurement and control solution thanks to the integration of a D/8 optical structure, simultaneous SCI/SCE measurement technology, and a multi-aperture system. With impressive repeatability (ΔE*ab ≤ 0.03), the DS-620 is the optimal choice for factories and laboratories needing a versatile, high-precision device that still perfectly balances investment costs.

Outstanding Features

Simultaneous SCI and SCE Measurement Technology: The smart D/8 structure allows the device to simultaneously acquire both the true color data of the material (SCI – serving color formulation calculation) and the visually perceived color by humans (SCE – affected by surface roughness and gloss). This feature helps optimize measurement time and in-depth analysis.

Flexible Multi-Aperture System: The device is equipped with diverse illumination/signal reception apertures: 11mm/8mm for wide surfaces; 6mm/4mm for small details; and especially a 1*3mm narrow slit. As a result, the DS-620 can easily measure on all sample shapes, from flat surfaces and curved/beveled surfaces, to extremely small area components.

Reliable Stability (ΔE*ab ≤ 0.03): The device provides measurement results with high repeatability, excellently meeting industrial Pass/Fail evaluation standards, helping to maintain data consistency between production batches.

Smart Positioning Camera Integration: When measuring ultra-small details using the 4mm or 1*3mm apertures, the integrated camera system allows users to observe directly on the screen to accurately target the area to be analyzed, completely eliminating errors caused by misaligned operations.

Independent Operation Experience: The ergonomic design accompanied by a crisp color touch screen helps users easily view spectral graphs, color data, and store information directly on-site without relying on a computer.

Common Applications

Thanks to the combination of simultaneous SCI/SCE measurement and specialized apertures, the CHNSpec DS-620 excellently meets diverse applications:

• Plastics and Molded Components: Color inspection of plastic pellets, complex injection-molded products, and plastic surfaces with a mix of rough and glossy structures.
• Electronics & Automotive Interiors: Color measurement of small details such as buttons, phone casings, earphones, microchip slots, or car control buttons (maximizing the application of 4mm and 1*3mm apertures).
• Paints and Coatings: Evaluating the color deviation of electrostatic powder coatings and metal coatings, and inspecting color differences caused by surface gloss.
• Textiles & Footwear: Color analysis on woven fabrics, sewing threads, and synthetic leather patches with uneven surface textures.
