The CHNSpec DS-400 Series combines D/8 measurement geometry, SCI/SCE operation and ΔE*ab≤0.03 repeatability in a portable spectrophotometer platform. Its 400–700nm spectral range, approximately 1s measurement time and broad set of color indices support repeatable incoming inspection, production checks and laboratory color evaluation.
DS-400, DS-410 and DS-420 share intelligent automatic calibration, a 2.4-inch color screen, USB and Bluetooth connectivity, and support for Android, iOS, Windows and the WeChat mini program. The models differ in aperture flexibility, measurement-area positioning, UV illumination and accuracy qualification, allowing buyers to match the instrument to sample size and material type.
Key Features
-
D/8 geometry with SCI/SCE: supports measurements with specular reflection included or excluded for practical surface-color evaluation.
-
ΔE*ab≤0.03 repeatability: provides stable results for color comparison and quality-control workflows.
-
400–700nm spectral range: displays reflectance data across 31 wavelengths at 10nm intervals.
-
Flexible aperture system: select 4, 6 or 10 round and flexible aperture configurations according to the model and sample size.
-
Extensive color evaluation: supports more than 30 measurement parameters and nearly 40 evaluation illuminants.
-
Fast operation: completes a measurement in about 1s and supports single or 2–99-measure averages.
-
Automatic calibration: the supplied calibration base uses a durable zirconium reference to keep the instrument ready for measurement.
-
Connected data management: USB and Bluetooth connect the instrument with mobile and Windows software for color records and analysis.
-
Portable workflow: the 3.7V/3000mAh battery supports up to 8,000 continuous measurements per charge.
Applications
- Paint, coatings and plastics color consistency checks
- Textile, printing and packaging color quality control
- Automotive interior and manufactured-part inspection
- Incoming material inspection and production batch comparison
- Laboratory color measurement and digital color database management
Model Differences & Selection
-
DS-400: provides four aperture configurations at 11mm and 6mm with visual positioning and standard qualified measurement accuracy. Choose it for routine color control on conventional sample areas.
-
DS-410: expands to six aperture configurations at 11mm, 6mm and 3mm, adds camera positioning and carries first-level accuracy qualification. Choose it for more precise placement and smaller measurement areas.
-
DS-420: offers ten aperture configurations at 11mm, 10mm, 6mm, 5mm and 3mm, plus camera positioning, UV illumination and first-level accuracy qualification. Choose it for the widest sample-size flexibility and measurements involving fluorescent materials.
Why Choose the DS-400 Series?
This series provides a clear upgrade path from routine visual-positioned color checks to camera-assisted and UV-capable measurement. Shared software, calibration and operating workflows simplify instrument standardization across quality-control teams while preserving model choice for different samples and inspection requirements.
