CHN SPEC DS-420 Spectrophotometer (D/8, dE*ab≤0.03, Φ11mm/Φ10mm/Φ6mm/Φ5mm/Φ3mm)

CHN SPEC DS-420 Spectrophotometer (D/8, dE*ab≤0.03, Φ11mm/Φ10mm/Φ6mm/Φ5mm/Φ3mm)

The CHNSpec DS-420 Spectrophotometer is a new generation portable color measurement device, optimized to provide a perfect balance between high accuracy and measurement flexibility. Integrating a versatile D/8 geometric structure and a switchable 5-aperture measurement system, the DS-420 is a comprehensive solution for stringent color quality control (QC) on various sample shapes and sizes.

Outstanding Features:

Standard D/8 Optical Structure: Utilizing an integrating sphere to create a uniform diffuse light source on the sample surface. This structure minimizes errors caused by texture direction, roughness, or surface conditions, providing objective and stable measurement results.

Versatile 5-Aperture System: Featuring up to 5 aperture options (from large 11mm/10mm, medium 6mm/5mm to small 3mm), the device allows users to flexibly measure on large flat surfaces as well as easily access narrow details, curved surfaces, beveled edges, or components with limited areas.

Impressive Accuracy and Repeatability: With an extremely low error margin (ΔE*ab ≤ 0.03), the DS-420 provides excellent repeatability compared to many other handheld devices on the market. This helps factories maintain absolute color consistency for product batches over a long period.

Positioning Camera for Accurate Measurement: To maximize the effectiveness of the 3mm aperture, the device is integrated with an observation camera for the measurement area. Users can look directly at the screen to correctly align the measurement position, avoiding mistakenly measuring outside the target color area.

Smart Design, Independent Operation: The device features an ergonomic design, easy to operate with one hand. The built-in crisp color screen intuitively displays color data, spectral graphs, and Pass/Fail results directly on-site without needing a computer connection.
