CHN SPEC CRX-62 Non-Contact Color Spectrophotometer (45/0, dE*ab≤0.05)

CHN SPEC CRX-62 Non-Contact Color Spectrophotometer (45/0, dE*ab≤0.05)

The CHN SPEC CRX-62 Non-Contact Color Spectrophotometer (45/0 Geometry, dE*ab≤0.05) is a next-generation on-line color inspection instrument, specifically designed for modern industrial production lines. Setting itself apart from traditional handheld colorimeters, the CRX-62 utilizes advanced non-contact optical technology, enabling accurate color measurement of products directly on moving conveyors without affecting the sample surface.

Featuring a standard 45/0 geometry and an inter-instrument agreement of dE*ab≤0.05, the CHN SPEC CRX-62 serves as a comprehensive color quality control (QC) solution for industries such as textiles, coatings, plastics, paper, printing, and food processing.

Outstanding Features of CHN SPEC CRX-62

1. Non-Contact Measurement Technology – Absolute Sample Surface Protection

The CHN SPEC CRX-62 is engineered to measure color from a fixed distance without touching the product surface. This advantage makes the device the ultimate and ideal choice for materials with delicate or specific surfaces, such as wet coatings, liquid/gel foods, chemicals, or materials prone to scratching or deformation under physical contact pressure.

2. International Standard 45/0 Optical Geometry

The device adopts a 45-degree illumination / 0-degree viewing (45/0) geometry, precisely replicating the way human eyes perceive color in nature. This structure successfully eliminates the effect of specular reflection (Specular Component Excluded – SCE) caused by surface gloss, delivering measurement results that truly reflect the intrinsic color of the product.

3. Top-Tier Accuracy (dE*ab Less Than or Equal to 0.05)

With an extremely low color measurement repeatability of dE*ab less than or equal to 0.05 (when measuring a standard white plate 30 consecutive times), the CRX-62 ensures outstanding data consistency. The instrument is capable of detecting the smallest color discrepancies between different production batches, helping businesses minimize defect and waste rates effectively.

4. Optimized for Automation Integration (Inline / Online QC)

Real-Time Measurement: Seamlessly connects and transmits continuous data to the central control system, enabling real-time color quality monitoring as products run on the conveyor belt.

Durable Industrial Design: Constructed with a rugged body, excellent dust resistance, and ambient light immunity, guaranteeing stable 24/7 operation in harsh industrial factory environments.

Smart Communication: Supports multiple industry-standard communication ports (RS-485, Modbus, Ethernet, etc.), making it easy to integrate into PLC systems or automated robotic arms.

Practical Applications

Thanks to its high-speed, precise non-contact measurement mechanism, the CHN SPEC CRX-62 serves as a critical link in the production lines of:

• Paint & Coatings Industry: Inspects the color of coating films immediately after spraying or while the paint is still wet on coil coating lines for metal, wood, or plastic, without ruining the surface finish.
• Plastics & Polymer Sheet Industry: Continuously monitors the color of extruded plastic films, resin pellets, or large molded components as they emerge from high-temperature molds.
• Textiles & Footwear Industry: Performs online color measurement for fabric rolls and leather sheets running on high-speed weaving/dyeing machines to ensure color uniformity from the beginning to the end of the roll.
• Paper & Packaging Printing Industry: Integrated into paper making machines or industrial web printing presses to continuously monitor color density and color variations on the paper/ink surface.
• Food & Cosmetics Industry: Measures the color of powdered, granular, or liquid products (such as sauces, creams, soaps) on conveyor belts in a completely hygienic and food-safe manner.

CHN SPEC CRX-62 Non-Contact Color Spectrophotometer is a strategic hardware solution that empowers factories to shift from manual quality inspection to smart automation. This represents a sustainable investment that optimizes R&D processes, standardizes product color, and enhances corporate competitiveness.
