CHN SPEC CS-520 Spectrophotometer

CHN SPEC CS-520 Spectrophotometer

The CHN SPEC CS-520 Spectrophotometer is an outstanding upgraded version in the CHN SPEC portable color measurement device ecosystem. Not only does it possess high-precision optical measurement hardware, but the CS-520 also integrates wireless connectivity technology and automation features, helping to optimize user experience and improve work efficiency in quality control (QC) processes.

Outstanding Features

• International standard optical system (D/8, SCI+SCE): The device uses a diffuse illumination geometric structure with an 8-degree viewing angle (D/8). The simultaneous measurement mode of SCI (Specular Component Included) and SCE (Specular Component Excluded) helps users accurately evaluate the original color while recognizing the influence of surface gloss or roughness on color perception.
• Smart automatic calibration: The CS-520 is equipped with a magnetic calibration base (built-in white calibration tile). As soon as it is turned on or placed back on the base, the device automatically performs the calibration process without requiring the user to manually perform complex steps.
• Data synchronization via Bluetooth & Mobile App: The device supports seamless Bluetooth connection with smartphones (via a dedicated App). Users can easily store and share color data, create QC reports remotely, and access a massive color database to search for equivalent standard color codes.
• Stable full-spectrum CLED light source: Similar to high-end models, the device uses a full-spectrum balanced LED (CLED) band spanning the visible light range (400-700nm). This light source ensures outstanding accuracy when analyzing complex color gamuts and has a very long operating lifespan.
• High repeatability and reliability: The powerful sensor system helps the CS-520 achieve excellent repeatability at dE*ab ≤ 0.04, ensuring absolute data consistency when performing continuous measurements on the production line or among different batches.
