3nh YS4560plus 45/0 Geometry Spectrophotometric Colorimeter

Overview

The 3nh YS4560plus is a high-precision, portable spectrophotometric colorimeter engineered for industrial-grade color measurement under CIE No. 15–compliant 45/0 optical geometry. This configuration—featuring 45° annular illumination and 0° normal-axis detection—minimizes directional bias and specular influence, delivering highly reproducible reflectance data across matte, textured, and semi-gloss surfaces. Unlike 0/45 or diffuse/8° instruments, the 45/0 design ensures consistent response to surface topography variations common in traffic signage, automotive trim, coated plastics, and printed materials. The instrument employs a concave holographic grating spectrometer with a solid-state LED light source spanning 400–700 nm, enabling full-spectrum acquisition at 10 nm nominal resolution. A dedicated UV-emitting LED channel supports quantitative fluorescence correction and measurement of optically brightened samples—including retroreflective sheeting, security inks, and fluorescent pigments—without external accessories.

Key Features

• Compliant 45/0 optical architecture per CIE Publication 15:2018 and ISO 5-4:2022 for geometrically robust reflectance measurement.
• Dual aperture selection (Φ8 mm and Φ4 mm) optimized for macro- and micro-area sampling—critical for heterogeneous surfaces such as woven textiles, granular coatings, and segmented road markings.
• Integrated UV excitation source (365 nm peak) enabling ASTM E308–22–aligned fluorescence compensation and direct Y10 brightness factor calculation per GB/T 18833–2022.
• Built-in reference standards aligned with national regulatory benchmarks: GB 2893 (safety colors) and GB/T 18833 (retroreflective sheeting), supporting automated pass/fail evaluation against multi-dimensional tolerance zones (polygonal or rectangular).
• High repeatability performance: ΔE*ab ≤ 0.03 under MAV (Medium Area View) conditions—validated per ISO 13655:2017 using ceramic tile standards traceable to NIM (China National Institute of Metrology).
• Ruggedized portable housing with IP52-rated dust/moisture resistance, lithium-polymer battery support (>5,000 measurements per charge), and ergonomic trigger-actuated measurement interface.

Sample Compatibility & Compliance

The YS4560plus accommodates flat, curved, and slightly irregular surfaces typical of molded plastics, extruded profiles, painted metal substrates, and flexible films. Its 45/0 geometry inherently suppresses errors from surface gloss and texture—an advantage over integrating sphere systems when evaluating directional appearance attributes. Regulatory alignment includes full support for Chinese national standards governing road safety products (GB/T 18833–2022 for retroreflective coefficient and chromaticity coordinates; GB 2893–2022 for safety color tolerances). While not certified to ISO/IEC 17025, the instrument’s calibration traceability path follows manufacturer-established protocols compliant with JJF 1526–2015 (Calibration Specification for Colorimeters). Data output formats meet GLP documentation requirements, including timestamped spectral scans, operator ID fields, and measurement environment metadata (ambient temperature/humidity logging optional via software).

Software & Data Management

The bundled SpectraMagic NX-compatible PC software provides comprehensive color analysis, statistical process control (SPC), and database-driven quality auditing. It supports FDA 21 CFR Part 11–aligned user access control, electronic signatures, and audit trail generation—including parameter change history, calibration event logs, and result export timestamps. Users can define custom color difference thresholds per product line, generate ASQ Z1.4–based acceptance sampling reports, and export spectral data in JIS Z 8722–compliant CSV or CIE 15:2004–formatted .cie files. Cloud synchronization (via optional 3nh CloudLink module) enables cross-facility benchmarking and centralized QC dashboarding—particularly valuable for Tier-1 automotive suppliers managing color consistency across global production sites.

Applications

• Traffic engineering: Quantitative assessment of luminance factor (Y₁₀) and chromaticity coordinates (x, y) for road markings, signboards, and high-visibility garments per GB/T 18833 and EN 12899–1.
• Plastics & electronics: Batch-to-batch color verification of injection-molded housings, PCB solder masks, and elastomeric gaskets where surface finish variability challenges traditional sphere-based instruments.
• Textiles & printing: Spot measurement of dyed fabrics, digital prints, and flexographic inks—especially where metamerism evaluation requires full spectral reconstruction.
• Pigment formulation: Reference standardization for masterbatch producers and inkjet OEMs requiring stable ΔE tracking across spectral bands and observer angles.
• Quality assurance labs: Integration into IQ/OQ/PQ validation protocols for color-critical manufacturing lines operating under ISO 9001 or IATF 16949 frameworks.

FAQ

What standards does the YS4560plus comply with for traffic signage measurement?
It natively supports GB/T 18833–2022 and GB 2893–2022, including automatic calculation of Y₁₀, chromaticity coordinates, and luminance contrast ratios against defined polygonal tolerances.
Can the instrument measure fluorescent materials?
Yes—the integrated 365 nm UV LED enables excitation and spectral capture of fluorescence emission, allowing accurate colorimetric reporting under UV-containing illuminants per CIE 15:2018 Annex D.
Is spectral data export supported for third-party analysis?
Yes—raw reflectance spectra (360–740 nm at 10 nm intervals) are exportable in ASCII CSV and standardized .cie formats compatible with MATLAB, Python (scikit-learn), and commercial color formulation software.
How is calibration maintained across field deployments?
The device includes onboard ceramic white and black calibration tiles; daily verification is recommended per JJF 1526–2015, with annual recalibration traceable to NIM-certified reference standards.
Does the software support multi-user environments with role-based permissions?
Yes—SpectraMagic NX implements hierarchical user accounts, electronic signature workflows, and immutable audit trails meeting GLP and ISO/IEC 17025 documentation requirements.
