CHN SPEC DC-25D Handheld Spectrophotometer (D/8, dE*ab≤0.01, Φ11mm/Φ10mm/Φ6mm/Φ3mm)

CHN SPEC DC-25D Handheld Spectrophotometer (D/8, dE*ab≤0.01, Φ11mm/Φ10mm/Φ6mm/Φ3mm)

The CHN SPEC DC-25D Handheld Spectrophotometer is a high-performance standard color measurement device, designed to deliver absolute precision in color measurement. With an advanced optical system and user-friendly design, this device perfectly meets stringent color inspection requirements in industries such as coatings, plastics, textiles and dyeing, printing, and packaging.

Outstanding Features

International standard optical system (D/8, SCI+SCE): The device uses a diffuse illumination geometric structure, 8-degree viewing angle (D/8). The device is capable of simultaneously measuring both modes: Specular Component Excluded (SCE) and Specular Component Included (SCI), which helps accurately evaluate the original color and the influence of surface gloss on color.

Excellent stability and repeatability: The DC-25D is equipped with a high-sensitivity sensor, achieving a highly impressive repeatability of dE*ab ≤ 0.01. This ensures that measurement results are always consistent and reliable in consecutive measurements.

Flexible 4-aperture support: Unlike basic models, the DC-25D integrates 4 flexibly switchable measurement apertures including: Φ11mm, Φ10mm, Φ6mm, and Φ3mm. The diverse apertures help the device easily measure on various surface types, from wide flat surfaces to small details, curved surfaces, or complex components.

Durable, broad-spectrum light source: The device uses a high-precision LED system combined with a broad-spectrum lamp, providing a stable light source, long lifespan, and energy efficiency, ensuring accuracy throughout its usage.

Multi-platform connection: The device supports Bluetooth and USB connectivity, allowing fast data transmission to a computer (PC) or mobile devices (via App). Users can easily manage data, store standard samples, and export quality reports.
