CHN SPEC CRX-66 Spectrophotometer

CHN SPEC CRX-66 Spectrophotometer

The CHN SPEC CRX-66 Spectrophotometer is a non-contact color measurement device designed to be integrated directly into automated production lines. Unlike handheld or benchtop models, the CRX-66 continuously scans and analyzes the color of products moving on the conveyor belt without touching the surface. This helps detect and provide instant warnings for color deviations, optimizing the production process and minimizing scrap.

Outstanding Features

• Non-contact Measurement Technology: The device performs measurements at a safe distance from the material surface. This feature is especially important when measuring high-temperature products, wet samples (wet paint), powders, granules, or fast-moving materials on a conveyor belt without damaging the surface texture.
• Real-time Online Monitoring: The CRX-66 provides continuous color data in real-time. Results are transmitted directly to the central control system or management software, helping operators instantly grasp the color variation trend of the entire batch instead of just random sampling.
• Automation Integration (PLC & Alarms): The system supports various industrial communication ports (such as RS232, RS485, TCP/IP, I/O ports) to synchronize perfectly with PLC controllers. The device can automatically trigger an alarm bell or signal light when it detects colors falling outside the set tolerance range.
• High-precision Optical System: Despite measuring at a non-contact distance and in a dynamic environment, the machine is equipped with a powerful sensor system that eliminates light interference from the external environment, providing extremely stable repeatability equivalent to benchtop models.
• Durable Industrial Design: The sturdy alloy casing is designed to high dust and water resistance standards, protecting the lenses and optical components from harsh factory environments (dusty, humid, vibrating), ensuring durable 24/7 operation.

Practical Applications

With its continuous and automated measurement capabilities, the CHN SPEC CRX-66 is a core component for smart factories in the following fields:

• Coil Coating and Building Materials: Color consistency control for steel coils, color-coated sheets, glass, or ceramic tiles running on the production line.
• Textile/Dyeing and Paper Manufacturing: Continuous color measurement of fabric and paper rolls at high speeds to ensure color uniformity from the beginning to the end of the roll.
• Plastics and Thin Films Industry: Automatic color inspection of plastic sheets and nylon films during the extrusion process.
• Food Processing and Agricultural Products: Color sorting of agricultural products, color measurement of powdered or granular food running on conveyor belts.
