3nh the Large Aperture Spectrophotometer PS809 is a high-precision color measurement device specifically designed for complex samples and large-area surface color inspection. It adopts the D/8 (diffuse illumination, 8° viewing) optical geometry, conforming to CIE, ISO, ASTM and multiple national standards. Equipped with a 50 mm measurement aperture and a 120 mm integrating sphere, it achieves large-area uniform sampling, significantly improving the representativeness and stability of color measurement for non-uniform samples (e.g., textured surfaces, granules, fabrics, food, etc.).
The large aperture spectrophotometer PS809 incorporates a nano-integrated spectral device and a silicon photodiode array, supporting simultaneous SCI/SCE measurement. It is widely used in industries such as plastics & electronics, paints & inks, textiles & apparel, printing, ceramics, and food. It is an ideal choice for precise laboratory analysis and industrial production quality control.
1. 50 mm Measurement Aperture: Paired with a 120 mm integrating sphere, achieving uniform illumination and reception over a large area, effectively reducing measurement errors caused by sample texture, granules, and uneven color distribution. Particularly suitable for the color inspection of non-uniform samples such as rough surfaces, fabrics, food, powders, and granules.
2. D/8 Optical Geometry with Simultaneous SCI/SCE Measurement: Adopting diffuse illumination and 8° viewing geometry conforming to international standards, it simultaneously acquires SCI (Specular Component Included) and SCE (Specular Component Excluded) data, meeting the analytical requirements for gloss effects in different application scenarios and providing comprehensive data support for material appearance quality.

1. High Repeatability: After warm-up and calibration, 30 consecutive measurements on a standard white plate at 5-second intervals yield chromaticity value repeatability of ΔE*ab ≤ 0.03. Spectral reflectance standard deviation ≤ 0.1% (≤ 0.2% within the 400-700 nm band), ensuring the accuracy and stability of fine color difference identification.
2. Excellent Inter-Instrument Agreement: ΔE*ab ≤ 0.35 (average of measurements on 12 BCRA Series II color tiles), ensuring consistent color data transfer and benchmarking across multiple devices and laboratories, supporting group-level quality management.
3. Full-Band Accurate Acquisition: Measurement wavelength range 400-700 nm, wavelength interval 10 nm, half-bandwidth 10 nm, reflectance range 0-200%, achieving high-fidelity capture of sample spectral information.

1. Nano-Integrated Spectral Device: Adopting advanced nano-integrated spectral technology paired with a dual-row 20-group silicon photodiode array, it achieves high-speed, high-sensitivity spectral acquisition with a measurement time of approximately 1 second, significantly improving inspection efficiency.
2. Multiple Light Sources and Observation Conditions: Built-in over 40 standard observation light sources (D65, A, C, F-series, LED series, etc.) with 2°/10° observer angles, capable of simulating color appearance under various illumination environments to meet different industry standard requirements.
3. Rich Colorimetric Indices: Beyond conventional color spaces (CIE LAB, XYZ, LCh, HunterLab, etc.) and color difference formulas (ΔE*ab, ΔE*00, ΔE*cmc, etc.), it also supports whiteness WI (multiple standards), yellowness YI, staining fastness, color change fastness, strength, hiding power, color density CMYK, and other professional indices, comprehensively covering the quality control needs of industries such as plastics, textiles, coatings, and printing.

1. Smart Color Chart Matching: Built-in universal electronic color chart library for rapid matching from physical samples to industry-standard color chart numbers, improving color matching and quality inspection efficiency.
2. 7-inch Large Touchscreen: Equipped with a TFT true-color capacitive touchscreen, intuitively displaying spectral graphs/data, colorimetric values, color difference plots, pass/fail judgments, and color bias — clear results at a glance with smooth operation.
3. Massive Storage Capacity: Stores up to 1,000 master samples and 30,000 test samples, meeting the data storage and traceability requirements of industrial mass production inspection.
4. Cross-Platform Software Support: Accompanied by professional quality management software (download from official website), supporting in-depth data analysis, batch management, remote transmission, and report export, facilitating the construction of a digital color management system.
5. Multi-Language System: Built-in Simplified Chinese, English, Traditional Chinese, Russian, and other languages, adapting to global application scenarios.
