CHN SPEC DC-23D Handheld Spectrophotometer (D/8, dE*ab≤0.02, Φ11mm/Φ6mm)

CHN SPEC DC-23D Handheld Spectrophotometer (D/8, dE*ab≤0.02, Φ11mm/Φ6mm)

The CHN SPEC DC-23D Handheld Spectrophotometer is a color measurement device designed to be compact and durable while still possessing a modern optical technology platform. It is a powerful tool that helps manufacturers standardize color inspection processes, eliminating errors caused by human visual perception in industries such as plastics, coatings, printing, and textiles.

Outstanding Features

D/8 Optical System (SCI/SCE): Similar to high-end models, the device uses a diffuse illumination geometric structure with an 8-degree viewing angle (D/8). The SCI (Specular Component Included) and SCE (Specular Component Excluded) measurement modes help users flexibly evaluate both the actual color and the influence of surface gloss/roughness.

High Stability Repeatability: The device delivers reliable measurement results with a repeatability of dE*ab ≤ 0.02. This parameter fully meets strict quality control (QC) requirements, ensuring color consistency in mass production.

Integrated Dual Apertures: The device is equipped with 2 standard measurement apertures: Φ11mm and Φ6mm. Users can easily switch between the 11mm aperture (for flat, uniform surfaces) and the 6mm aperture (for smaller details or slightly curved surfaces) without needing to invest in a new machine.

Ergonomic and Intuitive Design: The device features a simple interface, a clear display screen, and smooth buttons, enabling rapid measurement operations. The streamlined design allows for a firm grip, preventing hand fatigue during continuous measurement.

Smart Connectivity: The DC-23D supports USB and Bluetooth connections, compatible with computer software (PC) and mobile applications. This makes it easy to store a database of standard colors, analyze tolerance charts, and export professional reports.
