CHN SPEC DC-26D Handheld Spectrophotometer (D/8, dE*ab≤0.01, Φ11mm/Φ10mm/Φ6mm/5mm/Φ3mm/1mm*3mm)

CHN SPEC DC-26D Handheld Spectrophotometer (D/8, dE*ab≤0.01, Φ11mm/Φ10mm/Φ6mm/5mm/Φ3mm/1mm*3mm)

The CHN SPEC DC-26D Handheld Spectrophotometer is a new generation Benchmark Portable Spectrophotometer. The device is equipped with a high-precision CMOS sensor system and a wide wavelength range from 360–780nm, enabling superior color measurement and material analysis even in industries demanding absolute precision such as coatings, textiles and dyeing, printing, plastics, and packaging.

Outstanding Features

International standard optical system (D/8, SCI+SCE): The device uses diffuse illumination with an 8-degree viewing angle (D/8) and supports simultaneous measurement of both modes: Specular Component Excluded (SCE) and Specular Component Included (SCI). This helps accurately evaluate the true color and the glossy/rough surface of the material.

Ultra-high accuracy and repeatability: The device achieves an extremely impressive repeatability of dE*ab ≤ 0.01, along with an inter-instrument agreement of only dE*ab ≤ 0.12. This ensures absolute data consistency among multiple devices across different factories or production lines.

Advanced dual light source system: The combination of a pulsed Xenon lamp (covering a wide spectrum, close to natural light) and high-precision LEDs ensures long-term stable operation, with a lifespan of up to millions of measurements.

Diverse and flexible measurement apertures: The device comes standard with up to 6 switchable measurement apertures: Φ11mm, Φ10mm, Φ6mm, Φ5mm, Φ3mm, and 1mm x 3mm. This design allows users to easily measure everything from wide flat surfaces to ultra-small samples, complex details, or curved surfaces.

Smart connection & Automatic calibration: The device supports the network calibration function (NetProf), which helps automatically diagnose and synchronize standard data. The machine also connects flexibly via Bluetooth/USB to a PC or mobile devices (Android, iOS) through a dedicated App for storage and report exporting.

Practical Applications

With the ability to extend the wavelength beyond the conventional visible spectrum (up to 780nm) and measure dozens of different indices (whiteness, yellowness, color fastness, color strength, etc.), the DC-26D is a comprehensive solution for:

• Research and Development (R&D) laboratories and Quality Control (QC) departments.
• Color measurement of electrostatic powder coatings, automotive paints, textiles, and footwear.
• Quality inspection of printing packaging, plastics, rubber, and even in food processing.
