Key Features and Technologies

• Advanced Color Index Analysis for Liquids: In addition to standard color spaces like CIE-Lab, XYZ, and Yxy, the device integrates specialized color indices for the liquid and chemical industries, such as: Transmittance, Haze, Platinum-Cobalt color index (Pt-Co / APHA), Gardner color index, Saybolt color index, ASTM D1500…
• Inter-Instrument Agreement: The variation between machines of the same series is extremely low, ensuring color data synchronization when enterprises deploy multiple DS-810N units across different branches or factories.
• Large Touch Screen & Intuitive Interface: Integrates a high-resolution touch screen directly on the body for selecting filters, setting tolerances, and reading results in the form of spectral line charts without requiring a mandatory PC connection.
• Professional PC Color Management Software: Connects to a computer via USB/RS-232 ports and comes with powerful data analysis software, helping store millions of samples, export QC reports as color charts and dynamic data tables, and providing strong support for color formula research.
• Calibration and Self-Diagnosis: The system automatically reminds users to calibrate and features sensors to self-check the status of the hardware, ensuring the equipment always operates under optimal technical conditions.

Practical Applications:

CHN Spec DS-810N is a powerful assistant in quality control (QC) and research & development for liquid, paste, or transparent film products:

• Food & Beverage Industry: Measuring the color and transparency of cooking oil, soft drinks, fruit juice, honey, soy sauce, beer, and wine.
• Cosmetics & Pharmaceutical Industry: Controlling the chromaticity of essential oils, perfumes, liquid detergents, pharmaceutical syrups, liquid excipients, and liquid creams.
• Chemical & Petroleum Industry: Measuring the color index of petroleum, industrial solvents, liquid asphalt, adhesives, and printing chemicals.
• Plastics & Glass Industry: Measuring the haze and total light transmittance of plastic sheets, optical glass, and solar control window films.
