CHN SPEC CS-650 Spectrophotometer
The CHN SPEC CS-650 Spectrophotometer is a professional color analysis device designed for stringent quality control (QC) requirements. What sets the CS-650 apart from basic models is its integrated camera system that helps users see the exact measurement position, thoroughly solving the difficulty of measuring samples with alternating patterns, textures, or small sizes.

Outstanding Features
- Measurement point positioning by Camera (Camera Viewfinder): This is the most valuable feature of the CS-650. Instead of estimating the measurement position by eye through the gap, users can directly observe the sample area under the aperture through the device’s screen. This is extremely useful when measuring small details on circuit boards, patterns on fabrics, or printed logos.
- International standard optical system (D/8, SCI+SCE): The device uses a D/8 diffuse illumination geometric structure. It supports simultaneous measurement of both SCI (Specular Component Included) and SCE (Specular Component Excluded) modes, helping to fully evaluate the original color and the influence of surface gloss.
- Full-spectrum CLED light source: The CS-650 uses a CLED (full-spectrum balanced LED) system to cover the visible light range (400-700nm). This light source overcomes the spectrum deficiency in specific color bands of conventional LEDs, ensuring accurate measurement results across all shades.
- Crisp color TFT screen: The device is equipped with a 2.4-inch TFT screen that displays true colors. Users can read technical parameters, spectral reflectance graphs, and Pass/Fail results directly on the device without needing a computer.
- Data management software (Color QC): The device connects to a computer via a USB port, accompanied by professional color management software. The software supports data analysis, tolerance setting, unlimited standard sample storage, and report exporting in multiple formats.
Practical Applications
With the help of the positioning camera and high accuracy, the CHN SPEC CS-650 is an ideal tool for:
- Textile and pattern printing industry: Accurately measure each color patch on fabrics with complex patterns or checkered stripes.
- Paints and coatings industry: Evaluate the color deviation of electrostatic powder coatings, automotive paints, and decorative paints.
- Plastics and rubber industry: Control the color of plastic components, plastic pellets, and household appliances.
- Electronic components & Automotive: Color measurement on machine parts and control panels with small and narrow areas.
