CHN SPEC CRX-60 Non-Contact Color Spectrophotometer (45/0, dE*ab≤0.1)

CHN SPEC CRX-60 Non-Contact Color Spectrophotometer (45/0, dE*ab≤0.1)

The CHN SPEC CRX-60 Non-Contact Color Spectrophotometer (45/0, dE*ab≤0.1) is a next-generation on-line color quality control (Online QC) instrument, providing a highly efficient automated measurement solution for manufacturing plants. Utilizing advanced optical technology, the device precisely determines product color indices from a fixed distance without direct contact with the sample surface, thereby ensuring absolute product protection and optimizing inspection speeds on the production line.

Featuring a (45/0, dE*ab≤0.1) measurement geometry, the CHN SPEC CRX-60 is an economical and reliable choice for the coatings, plastics, textiles, paper packaging, and food processing industries.

Outstanding Features of CHN SPEC CRX-60

1. Non-Contact Measurement – Flexible and Safe

The greatest advantage of the CHN SPEC CRX-60 is its ability to measure color from a distance without mechanical contact with the specimen. This completely eliminates the risk of scratching sensitive surfaces, prevents the deformation of flexible materials, and is exceptionally well-suited for measuring materials moving continuously on conveyor belts or substances in special states such as wet paint, chemicals, gel-like foods, and sticky powders.

2. 45/0 Optical Geometry Replicating Human Vision

The device adopts a 45-degree ring illumination and 0-degree viewing (45/0) geometry. This international standard optical structure effectively eliminates interference from surface gloss (SCE). Consequently, the instrument’s measurement results truly reflect how the human eye perceives color, providing high objectivity when evaluating color uniformity across different batches.

3. Accurate and Reliable Performance

With a color measurement repeatability of dE*ab less than or equal to 0.1 (when performing 30 consecutive measurements on a standard white plate), the CRX-60 guarantees high stability throughout production shifts. The device helps quickly detect color drift trends on the production line, assisting technicians in adjusting formulas promptly to minimize defect and waste rates.

4. Industrial-Grade Design for Easy Inline Integration

• Real-Time Operation: The device continuously scans and transmits color data to the central monitoring system, enabling businesses to manage product quality second-by-second on the conveyor belt.
• Smart Connectivity: Fully supports popular industrial communication protocols such as RS-485, Modbus, Ethernet, etc., making it easy to synchronize with PLC control systems or integrate into automated robotic arms.
• Durable Mechanical Structure: The rugged, tightly sealed body offers excellent dust resistance and immunity to factory ambient light interference, ensuring durable 24/7 equipment operation.

Practical Applications:

Thanks to its high-speed and non-contact online measurement mechanism, the CHN SPEC CRX-60 is widely used across various production lines:

• Plastics & Rubber Industry: Performs online color measurement for extruded plastic film rolls, resin pellets, or household plastic components right as they emerge from high-temperature molds.
• Paint & Color-Coated Steel Industry: Inspects and monitors color variations of the coating film immediately after spraying or on continuous coil coating lines without affecting the partially cured paint layer.
• Textiles & Synthetic Leather Industry: Installed above the conveyor belts of weaving or dyeing machines to verify color uniformity from the beginning to the end of fabric rolls, enabling early detection of edge-to-edge color shading.
• Paper & Packaging Printing Industry: Measures color density and color variations on the surface of paper rolls or cardboard packaging running at high speeds on industrial web printing presses.
• Building Materials Industry: Automatically monitors the surface color of ceramic tiles, gypsum ceiling boards, or faux-wood wall panels, replacing the error-prone manual visual inspection method.

The CHN SPEC CRX-60 Non-Contact Color Spectrophotometer is the optimal hardware solution to digitize online color inspection workflows. This represents a smart, highly cost-effective investment that helps businesses standardize their quality control (QC) procedures, optimize operational efficiency, and strengthen brand reputation in the market.
