Product Description
The YD series grating spectrophotometers, including models like YD5050 and YD5010, are engineered for exceptional color measurement and density analysis across various industrial applications. These instruments adhere to international standards such as ISO 5-4 and CIE No. 15, utilizing a 45/0 geometric optical structure (45° ring-shaped illumination, 0° viewing angle) to ensure consistent and accurate readings. Designed for sectors like ink printing, textile dyeing, film processing, and plastics, they facilitate comprehensive quality management from prepress to final output.
Key features include a robust hardware configuration with a concave grating spectral splitter and a 256-pixel dual-array CMOS image sensor, enabling high-speed measurements within approximately 1.5 seconds. The devices support multiple measurement conditions per ISO 13655—M0 (CIE Light Source A), M1 (D50), M2 (UV excluded), and M3 (polarized filter)—allowing flexibility for different materials and environments. Users can measure critical parameters such as optical density, dot area, dot gain, overprint rate, and print contrast, with color spaces like CIELAB, XYZ, Yxy, and LCh, and illuminants including D65, A, C, and F-series.
Operational efficiency is enhanced through a 3.5-inch TFT capacitive touch screen for intuitive navigation and one-touch measurement capabilities. The instruments offer single or average measurement modes, storage for up to 10,000 data points, and connectivity via USB or Bluetooth for seamless integration with PC software like SDQC. This software expands functionality to data analysis, report generation, and cloud storage, supporting tasks such as real-time monitoring, trend analysis, and compliance documentation.
With a compact design (184x77x105mm) and lightweight build (approx. 600g), the spectrophotometers are portable for on-site use. They are powered by a long-lasting lithium battery, supporting up to 5,000 measurements per charge, and have an illuminant lifespan exceeding 3 million cycles. Applications span printing shops, laboratories, paper mills, and research institutions, ensuring versatility in color consistency and process control. The inclusion of polarizing filters, customizable apertures (e.g., Φ2mm, Φ4mm, Φ8mm for YD5010), and options like micro-printers further customize the tool for specific needs, promoting efficiency in quality assurance workflows.
