Overview
The 3nh YS4510 Portable 45/0 Spectrophotometric Colorimeter is engineered for high-accuracy color measurement in industrial quality control environments where portability, geometric compliance, and spectral fidelity are critical. It implements the CIE No. 15–recommended 45/0 optical geometry—featuring 45° circumferential illumination and 0° axial detection—ensuring consistent, geometry-controlled reflectance measurement of non-fluorescent and fluorescent samples alike. Unlike diffuse/8° or d/0 instruments, the 45/0 configuration minimizes directional surface effects (e.g., texture, gloss, orange peel), making it especially suitable for flat, matte, or structured surfaces common in traffic signage, coated plastics, textiles, printed materials, ceramics, and automotive trim. The device employs a concave holographic grating and a 256-pixel dual-array CMOS detector to acquire full spectral reflectance data across the visible spectrum (400–700 nm) with high signal-to-noise ratio and thermal stability. Its LED-based illumination system integrates UV-emitting and UV-filtered modes, enabling accurate assessment of optical brighteners and fluorescent pigments under standardized illuminants.
Key Features
- CIE No. 15–compliant 45/0 optical geometry, validated against GB/T 3978, GB 2893, GB/T 18833, ISO 7724-1, ASTM E1164, and DIN 5033 Teil 7
- Modular aperture system supporting user-selectable single-spot measurement areas: Φ2 mm, Φ4 mm, or Φ8 mm—optimized for small features (e.g., road marking stripes), textured substrates, or large uniform fields
- Multi-illuminant capability covering 12 standard light sources including D65 (daylight), A (incandescent), CWF (cool white fluorescent), TL84 (retail lighting), and specialized traffic-signage illuminants (e.g., DLF, TL83)
- High-stability ceramic standard white tile with enhanced contamination resistance and long-term reflectance retention
- 3.5-inch capacitive touchscreen TFT display with intuitive icon-driven interface; operable without PC connection
- Dual communication interface: USB 2.0 for high-speed data transfer and Bluetooth 2.1 for wireless synchronization with mobile or desktop platforms
- Onboard storage capacity exceeding 20,000 measurement records—including spectral curves, CIE XYZ, L*a*b*, L*C*h°, ΔE*ab/ΔE00, whiteness/yellowness indices, and custom color difference formulas
- Support for both 2° and 10° standard observer functions, enabling conformance to application-specific visual evaluation conditions
Sample Compatibility & Compliance
The YS4510 accommodates a broad range of solid, non-translucent samples—from rigid plaques and painted panels to flexible fabrics, coated papers, and ceramic tiles—provided surface curvature and roughness fall within the constraints of 45/0 geometry. Its fixed-angle illumination eliminates sensitivity to sample tilt, improving operator-to-operator reproducibility in field or production-line use. For regulatory applications, the instrument supports traceable color assessment per ISO 3664 (graphic technology), ASTM D2244 (color difference calculation), and EN 12831 (road marking retroreflection color criteria). Built-in traffic-sign color gamut templates and luminance factor (Y) validation routines align with GB/T 18833 and EN 1436, facilitating pass/fail decisions for roadside safety materials without external software interpretation.
Software & Data Management
The included PC-based color management software (ColorExpert) provides comprehensive data analysis, statistical process control (SPC), and reporting tools compliant with GLP and GMP documentation requirements. Features include audit trail logging (user actions, calibration events, parameter changes), multi-sample comparison charts, tolerance ellipsoid visualization in CIELAB/CIEDE2000 space, and export to CSV, PDF, or XML formats for integration into LIMS or ERP systems. The software supports FDA 21 CFR Part 11–aligned electronic signatures and role-based access control when deployed in regulated manufacturing environments. Spectral data files adhere to the CGATS.17 (ISO 12641-2) format, ensuring interoperability with third-party color formulation and matching platforms.
Applications
- Traffic engineering: Verification of chromaticity coordinates and luminance factors for retroreflective road markings per GB/T 18833 and EN 1436
- Plastics & electronics: Batch-to-batch color consistency monitoring for injection-molded housings, PCB solder masks, and display bezels
- Textile & apparel: Shade matching across dye lots and substrate types (cotton, polyester, blends) under retail-relevant illuminants (TL84, CWF)
- Paint & coatings: Quantitative evaluation of metallic flake orientation effects, weathering-induced hue shift, and batch conformity to AAMA 2604/2605 specifications
- Printing & packaging: Spot color verification against ISO 12647-2 standards; measurement of ink density, dot gain, and substrate metamerism
- Ceramics & tiles: Glaze color uniformity assessment across kiln loads, including high-temperature stability tracking
FAQ
Does the YS4510 support fluorescence correction for optically brightened samples?
Yes—the instrument includes selectable UV-included and UV-excluded measurement modes, allowing direct comparison of fluorescent contribution under standardized illuminants such as D65 and C.
Can measurement data be exported in machine-readable formats for automated QA reporting?
Yes—CSV, XML, and CGATS.17-compliant spectral data exports are supported, with optional timestamping, operator ID tagging, and batch metadata embedding.
Is the 45/0 geometry suitable for measuring curved or glossy automotive parts?
The 45/0 geometry is not recommended for highly curved or specular surfaces; for such applications, a sphere-based d/8° instrument with gloss compensation is advised. The YS4510 is optimized for planar or gently contoured matte-to-satin finishes.
How often does the instrument require recalibration?
Daily verification using the supplied white tile is recommended before critical measurements; full recalibration is required after physical shock, temperature excursions >10°C, or every 30 days of continuous operation.
Does the software support multi-instrument fleet management and centralized database synchronization?
Yes—ColorExpert supports network deployment with shared spectral libraries, centralized tolerance definitions, and synchronized firmware updates across distributed YS4510 units.
