DS‑173 Portable D/8‑SCI Spectrophotometer | UV‑Switchable Color Difference Meter for Industrial Color QC
The DS-173 utilizes the internationally standard D/8 SCI measurement geometry. It is suitable for regular color measurement and color difference quality control across materials such as plastics, coatings, inks, printing, textiles, leather, ceramics, stone, and paper.
The instrument is equipped with a full-band balanced LED light source along with a UV light source that can be independently turned on or off. For regular samples, it can measure metrics such as color, color difference, whiteness, yellowness, blackness, color density, and opacity. For samples containing fluorescent whitening agents or fluorescent pigments, users can further analyze the impact of fluorescent components on color by comparing data gathered when the UV light source is turned on versus off.
Combined with a Φ11mm aperture, various standard illuminants, 2°/10° standard observers, standalone color matching capabilities, and dedicated software, the device seamlessly handles everything from rapid on-site quality inspection to professional color data management.
I. Six Core Selling Points
1.Professional Spectral Measurement
D/8 SCI geometry outputs spectral reflectance and multidimensional color data, allowing for rapid color measurement, color comparison, and color difference determination.
2.Switchable UV Source (On/Off)
Measures both regular and fluorescent materials, enabling comparative analysis of fluorescence impacts on color, whiteness, and yellowness.
3.Φ11mm Large Aperture
Captures color information over a larger surface area in a single scan, reducing interference caused by grain, texture, and localized color irregularities.
4.Multi-Illuminant + Dual Field of View
Supports D50, D65, A, and F series illuminants, multiple LED light sources, as well as 2°/10°standard observers.
5.Comprehensive Professional Metrics
Supports Lab, LCh, XYZ, and various color difference formulas, alongside indexes like whiteness, yellowness, blackness, color density, and opacity.
6.Standalone Color Matching & Software Management
Features standalone color matching, custom color card libraries, and a storage capacity of up to 10,000 records. Connects smoothly to Windows software.
II. Applications Widely utilized for color quality control across multiple industries
