CRX-66 Inline Spectrophotometer
The CRX-66 Inline Spectrophotometer is a non-contact, high-precision color measurement instrument engineered for continuous, real-time monitoring of product color during manufacturing. Designed for integration with assembly lines, robotic arms, and process control systems, the CRX-66 performs rapid and accurate color measurements without touching, contaminating, or damaging the sample surface. Featuring 45/0 geometry (45° annular illumination / 0° measurement), a built-in automatic calibration system, and LED full-band balanced illumination, it ensures exceptional accuracy and long-term operational stability. The CRX-66 achieves repeatability of ≤0.02 dE*ab and inter-instrument agreement of ≤0.25 dE*ab, meeting stringent international color measurement standards (CIE, ISO, ASTM, DIN). Ideal for on-line color quality control of wet films, coatings, plastics, packaging materials, and painted surfaces, the CRX-66 provides instant digital feedback for process optimization and product consistency.
