3nh CR-10Plus Portable High-Accuracy Spectrophotometric Colorimeter

Overview

The 3nh CR-10Plus is a portable, high-precision spectrophotometric colorimeter engineered for laboratory-grade color measurement in industrial quality control and R&D environments. It operates on the CIE-compliant d/8° integrating sphere geometry with dual-mode SCI (Specular Component Included) and SCE (Specular Component Excluded) measurement capability—enabling accurate characterization of both matte and glossy surfaces. The instrument employs a planar diffraction grating optical system coupled with a dual-row, 24-element silicon photodiode array sensor, delivering high spectral resolution across the visible spectrum (400–700 nm). Its full-spectrum LED illumination—including independently controllable UV component—ensures uniform radiance distribution without spectral gaps, eliminating measurement bias associated with narrow-band white LEDs. Designed to meet international metrological standards including CIE No. 15, ISO 7724-1, ASTM E1164, DIN 5033 Teil 7, and GB/T 3978, the CR-10Plus supports traceable color data acquisition under D65, A, C, D50, F2, F7, and F11 illuminants, with 2° and 10° standard observer options.

Key Features

• High-fidelity optical architecture: Planar grating spectrometer with 24-channel silicon photodiode array ensures stable signal-to-noise ratio, minimal thermal drift, and immunity to saturation under strong illumination or low-light sensitivity degradation.
• Dual-aperture measurement system: Interchangeable Φ8 mm / Φ10 mm and Φ4 mm / Φ5 mm measurement ports accommodate flat, curved, textured, or small-area samples—critical for electronics housings, automotive trim, textile swatches, and pharmaceutical tablets.
• Intelligent non-contact calibration base: Integrated motorized lift mechanism enables automated white tile verification using a certified reference tile (R ≥ 95% reflectance, uniformity ±0.2%); eliminates manual alignment error and improves long-term calibration stability.
• Multi-platform software ecosystem: Native support for Windows desktop applications, Android and iOS mobile apps, WeChat Mini Programs, and HarmonyOS—facilitating real-time data synchronization, cloud-based color database management, and audit-ready reporting.
• Ergonomic industrial design: Optimized grip contour, capacitive 3.5-inch TFT touchscreen, and tactile measurement button placement reduce operator fatigue during high-throughput sampling; IP52-rated enclosure resists dust ingress and incidental moisture exposure.
• Metrological performance: Repeatability of ΔE*ab ≤ 0.04 (measured on stabilized white tile at 5 s intervals, n=30), inter-instrument agreement ≤ 0.3 ΔE*ab (BCRA Series II 12-tile set), meeting ISO 13655:2017 requirements for Class II colorimetric instruments.

Sample Compatibility & Compliance

The CR-10Plus accommodates diverse sample geometries—including rigid panels, flexible films, powders (with optional powder test kit), liquids (in cuvettes), and irregularly shaped components—via mechanical stabilization aids such as positioning guides and camera-assisted framing. Its UV-enabled mode supports fluorescence correction for optically brightened materials (e.g., detergents, paper, textiles), while SCI/SCE toggle allows differentiation between total reflectance and surface appearance metrics. Regulatory compliance extends to GLP/GMP-aligned workflows: measurement logs include timestamped metadata, user ID, instrument serial number, calibration status, and environmental conditions (temperature/humidity)—supporting FDA 21 CFR Part 11–compliant electronic records when paired with validated software modules.

Software & Data Management

The bundled SpectraMagic NX-compatible PC software and cross-platform mobile applications provide full CIE color space conversion (CIELAB, CIELCH, XYZ, Yxy, RGB), advanced color difference algorithms (ΔE*ab, ΔE*cmc, ΔE*94, ΔE*00), whiteness/yellowness indices (ASTM E313, D1925), and fastness rating calculations (AATCC, ISO 105). Data export supports CSV, XML, and PDF formats with customizable templates for internal QA reports or supplier-facing documentation. Cloud integration enables centralized spectral library hosting, multi-site color standard synchronization, and version-controlled recipe management—essential for global supply chain color consistency programs.

Applications

The CR-10Plus serves as a primary color verification tool across regulated and high-tolerance industries: QC labs in automotive OEMs validate paint gloss and hue deviation against master standards; medical device manufacturers verify polymer batch consistency per USP ; cosmetic formulators monitor pigment dispersion stability in emulsions; food packaging producers assess ink density and substrate metamerism; and academic researchers quantify spectral reflectance profiles for material science studies. Its portability supports in-line measurements at production stations, warehouse receiving docks, and field service operations—without sacrificing metrological rigor.

FAQ

What calibration standards does the CR-10Plus support?
It includes factory-calibrated ceramic white and black tiles traceable to NIM (China National Institute of Metrology); optional NIST-traceable calibration kits are available for ISO/IEC 17025-accredited laboratories.
Can the CR-10Plus measure fluorescent or phosphorescent materials?
Yes—its integrated UV LED (365 nm peak) enables excitation-controlled measurement with selectable UV-on/UV-off modes, supporting ASTM E308 and ISO 13655 fluorescence compensation protocols.
Is spectral data export supported for third-party analysis?
Yes—full 10 nm interval reflectance spectra (400–700 nm) can be exported in ASCII format for use in MATLAB, Python (NumPy/Pandas), or proprietary spectral modeling tools.
How is data integrity maintained during wireless transmission?
Bluetooth 5.0 connection uses AES-128 encryption; all transmitted datasets include cryptographic checksums and embedded digital signatures to prevent tampering or truncation.
Does the instrument comply with color measurement standards for pharmaceutical packaging?
Yes—it satisfies ICH Q5C stability testing requirements for color change assessment and aligns with USP polymer identification via spectral fingerprinting when used with reference libraries.
