The AELAB DS-400/410/420 Colorimeter is an advanced portable instrument designed for precise color analysis across laboratory, industrial, and production applications. It provides automatic calibration, SCI/SCE geometry, and stable repeatability of ΔE*ab ≤ 0.03, supporting more than 30 color indices for accurate evaluation.
Equipped with full-band balanced LED illumination and optional UV measurement, the DS-400/410/420 delivers consistent reflectance data under multiple light sources, ensuring reliable and traceable color comparison results.
The instrument features a durable ergonomic structure with a 2.4-inch full-color touchscreen display. It integrates a silicon photodiode array (double 16 groups) and a 40 mm integrating sphere for uniform light distribution. The DS-420 model includes UV-enhanced LEDs for fluorescent sample measurement and a high-definition observation camera for precise sample alignment.
The colorimeter quantifies color reflectance and chromatic parameters in the 400–700 nm wavelength range using a nanometer-integrated spectral detection system. Users can perform single or averaged measurements, with data processed according to CIE-Lab, HunterLab, XYZ, and other international color spaces. Measurement time is approximately 1 second per test.
The DS Series interfaces via USB or Bluetooth and supports Android, iOS, and Windows platforms through the dedicated AELAB application and WeChat applet. Data storage includes 10,000 internal records with extended app-based mass storage for GLP-compliant traceability.
