AELAB Colorimeter DS-200/DS-210/DS-220 – Portable D/8 Color Difference Meters with UV Option

The AELAB Colorimeter DS-200/DS-210/DS-220 adopts a double optical path design to improve repeatability accuracy to ΔE*ab ≤ 0.03. The instruments support 30+ measuring indicators including color difference, whiteness, and yellowness, and provide nearly 40 evaluation light sources including UV for fluorescent color measurement.

The DS-200/DS-210/DS-220 are equipped with interchangeable measuring calibers, a built-in high-definition camera (DS-210/DS-220) for accurate positioning, and an automatic calibration base that stabilizes long-term performance. Mobile apps (WeChat applet, Android, Apple, Hongmeng) and the ColorExpert PC system enable comprehensive color management.

⚙️ Design & Construction

Each AELAB DS-200/DS-210/DS-220 colorimeter utilizes D/8 geometry with SCI, a full-band balanced LED light source (DS-220 adds UV), and a 40 mm integrating sphere. The silicon photodiode array (double 16 groups) captures reflectance over 400–700 nm with 10 nm intervals. A 2.4-inch full-color display supports field use, while USB and Bluetooth provide data exchange. Power is supplied by a 3.7V/3000 mAh rechargeable battery rated for 8000 continuous tests; the light source is specified for 10 years or 1 million tests.

🔬 Working Principle / Testing Method

The instrument measures surface reflectance and calculates CIE-Lab, CIE-LCh, HunterLab, CIE-Luv, XYZ, Yxy, RGB, and multiple color difference metrics (ΔE*ab, ΔE*cmc, ΔE*94, ΔE*00). It quantifies WI (ASTM E313-10/E313-00/E313-73, CIE, ISO2470/R457, AATCC Hunter, Taubeberger, Stensby), YI (ASTM D1925/E313-00/E313-73), Blackness (My, dM), Color Fastness, Tint (ASTM E313-00), CMYK density (A,T,E,M), Mlim, Munsell, Opacity, and Color strength. Measurement options include single reads or averaged sequences from 2 to 99, with typical cycle time about 1 second.

💡 Key Advantages

• Double optical path enhances repeatability to ΔE*ab ≤ 0.03 for rigorous QC
• Interchangeable apertures (Ø11 mm/Ø6 mm/Ø3 mm depending on model) adapt to samples from textiles to plastics
• Nearly 40 illuminants, including LED series and daylight/tungsten types, support cross-light-source evaluation
• UV capability on DS-220 enables fluorescent color measurement
• Automatic calibration base (DS-210/DS-220) stabilizes instrument drift over long-term use
• Integrated HD camera (DS-210/DS-220) improves target alignment and documentation
• Data connectivity via Bluetooth and USB plus ColorExpert PC software and mobile apps for GLP-style traceability

🔗 Connectivity & Integration

USB and Bluetooth interfaces connect the colorimeter to Windows PC software (ColorExpert) and mobile platforms (Android, iOS, WeChat applet, Hongmeng). Data export, storage (instrument: 10000 records; APP: mass storage), and multi-language support (Chinese/English) facilitate laboratory and production workflows.

🧠 Model Insight

🧪 Testing Applications

The AELAB DS-200/DS-210/DS-220 colorimeters are suited to QC and R&D color analysis for plastics, coatings, textiles, printing, packaging, building materials, and consumer products. They quantify color difference, whiteness/yellowness, opacity, density, and related indices under multiple illuminants; DS-220 additionally evaluates fluorescent materials with UV.
