Liquid Spectrophotometer TS4020: Precision Color Analysis for Liquids

The TS4020 is a state-of-the-art liquid spectrophotometer designed for high-precision color and chromaticity analysis of liquids. Engineered with a D/0 geometric optical structure, a full-spectrum LED light source, and an advanced dual-array sensor system, it delivers fast, accurate, and repeatable results across a comprehensive range of liquid color indices. Its ability to perform micro-volume transmission measurements makes it an indispensable tool for quality control and research in the chemical, food and beverage, petrochemical, and pharmaceutical industries.

Key Features:

• Comprehensive Chromaticity Indicators: The TS4020 measures an extensive array of color indices, including transmittance, Gardner, Saybolt, APHA/Pt-Co, and ASTM D1500, as well as pharmacopoeia and industry-specific scales like EBC (beer) and ICUMSA (sugar). This ensures full compliance with diverse international standards.

• Exceptional Accuracy and Consistency: With spectral transmittance repeatability within 0.05% and inter-instrument agreement under ΔE*ab 0.2, the TS4020 guarantees reliable and consistent data. This is crucial for maintaining quality control across multiple production lines or laboratory locations.

• Advanced D/0 Optical Geometry: Utilizing a D/0 (diffuse illumination, 0° viewing) optical structure, the TS4020 supports in-depth color analysis and ensures compliance with major standards such as ASTM D1003, CIE No.15, and GB/T 3978.

• Micro-Volume Measurement: The sophisticated optical design enables precise light transmission control, allowing for accurate measurements with sample volumes as small as 1 mL. This minimizes waste and is ideal for analyzing valuable or limited samples.

• Full-Spectrum LED Light Source: The long-life, full-spectrum LED light source covers a wavelength range of 360–780 nm, providing stable illumination and highly accurate color rendering for over 3 million measurements.

• Dual-Array Sensor for Speed and Precision: Equipped with high-performance dual 40-array silicon photodiode sensors, the instrument captures the full spectrum in under a second, significantly improving workflow efficiency without sacrificing precision.

• Intelligent and User-Friendly Operation: The device features a 7-inch capacitive touchscreen with an intuitive interface for easy navigation. Real-time data, including spectra and pass/fail results, are displayed clearly. It also includes built-in intelligent zero calibration, which automatically adapts to different environments to maintain measurement accuracy.

• Powerful Quality Management Software: The TS4020 comes with robust PC software for advanced chromaticity analysis, detailed test reporting, and customizable data management, making it an ideal solution for professional quality control environments.

Industry Applications: The versatility and precision of the TS4020 make it an essential tool for:

• Chemical Processing: Monitoring color consistency in solvents, resins, and other chemicals.
• Food and Beverage: Ensuring quality control for oils, syrups, juices, and alcoholic beverages.
• Petrochemical Analysis: Measuring the color of fuels, oils, and waxes according to ASTM standards.
• Pharmaceuticals: Verifying the color and clarity of liquid medicines to meet pharmacopoeia requirements.
