Overview
The 3nh NR60CP+ is a high-precision, handheld colorimeter engineered for reliable color measurement across heterogeneous surfaces—including plastics, liquid coatings, powder coatings, and metallic finishes with sparkle or gonio-apparent effects. It operates on the CIE-compliant 8°/d (8-degree illumination, diffuse viewing) optical geometry, ensuring conformity with ISO 7724-1, ASTM E308, and GB/T 3978 standards. Unlike traditional single-geometry instruments, the NR60CP+ integrates dual-aperture capability (Φ8 mm standard platform and Φ4 mm tapered probe), enabling consistent data acquisition from flat panels, curved substrates, recessed cavities, and textured metallics—critical in automotive trim, appliance finishing, and industrial coating QC workflows. Its full-spectrum LED illuminant replicates daylight (D65), incandescent (A), and fluorescent (F2/F7/F11) spectral power distributions without UV component degradation, delivering stable output over >1.6 million measurements (typical lifetime ≥5 years). The dual-CMOS optical path architecture minimizes stray light interference and enhances signal-to-noise ratio, directly supporting sub-ΔE*ab 0.03 repeatability under controlled lab conditions.
Key Features
- Dual interchangeable apertures: Φ8 mm platform for large-area uniform surfaces and Φ4 mm tapered probe for concave, narrow-gap, or irregular geometries—both calibrated to national metrological standards (CNAS-accredited verification available).
- Full-spectrum LED illumination with programmable CIE-standard observers (10°) and 12 selectable illuminants (D65, A, C, D50, F2–F12), enabling cross-illuminant color difference evaluation per ISO/CIE guidelines.
- Comprehensive color space support: CIE LAB, XYZ, LCh, RGB, LUV; seven industry-standard ΔE formulas including ΔE*ab, ΔE*00, ΔE*94, ΔE*CMC (1:1 & 2:1), and ΔE(h); plus whiteness (ASTM E313, ISO R457, Hunter), yellowness (ASTM E313), and fastness indices (staining & color change per ISO 105-A02).
- Integrated dual-positioning system: visible LED ring illumination + crosshair reticle for precise targeting—eliminating parallax error during handheld operation on glossy or reflective substrates.
- Robust portable architecture: IP52-rated enclosure, 205 × 67 × 80 mm footprint, 500 g mass, and 3.7 V / 3200 mAh rechargeable Li-ion battery supporting >6,000 measurements per charge.
- TFT 2.8″ true-color display (16:9 aspect ratio) with intuitive icon-driven UI; no PC dependency required for pass/fail judgment, delta-L/a/b reporting, or directional color deviation mapping.
Sample Compatibility & Compliance
The NR60CP+ accommodates solid, semi-solid, and particulate samples—including injection-molded plastic parts, spray-applied OEM coatings, anodized aluminum, PVD-finished hardware, and dry pigment powders (with optional powder test kit). Its 8°/d geometry mitigates specular component exclusion issues common in metallic and pearlescent systems, while the Φ4 mm probe enables localized assessment of weld seams, grilles, or engraved logos. All optical components comply with CIE Publication No. 15:2018, ISO 7724-2:2020, and GB/T 3978–2008. Inter-instrument agreement is validated against BCRA Series II ceramic tiles (ΔE*ab ≤ 0.4 average), meeting ISO 13655:2017 requirements for multi-unit color management networks. Data traceability supports GLP/GMP-aligned workflows via timestamped audit logs and user-defined sample IDs.
Software & Data Management
The included CQCS3 Quality Control Software (Windows-compatible, downloadable from 3nh official site) enables full spectral data export (CSV, TXT), statistical process control (SPC) charting (X-bar/R, Cp/Cpk), tolerance zone definition (ellipsoidal or rectangular), and batch-level compliance reporting. Raw reflectance spectra (10 nm resolution across 400–700 nm) are stored with metadata (operator ID, time stamp, aperture used, illuminant/observer). Software enforces 21 CFR Part 11–compatible electronic signatures, role-based access control, and immutable audit trails—essential for regulated environments in automotive Tier-1 supply chains and ISO 9001-certified manufacturing sites. USB 2.0 interface enables offline firmware updates and secure data transfer without cloud dependency.
Applications
This instrument serves as a primary color verification tool in production-critical settings where spectral fidelity and geometric flexibility are non-negotiable: incoming raw material inspection (resin pellets, pigment dispersions), in-process coating line monitoring (automotive clearcoats, coil coatings), final assembly color matching (consumer electronics housings, kitchen appliances), and supplier qualification audits (OEM color submission packages). It is routinely deployed by quality labs in Tier-1 automotive suppliers (e.g., Faurecia, Magna), global paint manufacturers (AkzoNobel, PPG), and contract electronics manufacturers (Foxconn, Flex) for conformance to internal color specifications (e.g., GMW14872, Ford WSS-M99P1111-A, BMW GS95024) and international standards (ISO 12647-2, ISO 8254-1).
FAQ
Does the NR60CP+ support measurement of metallic or effect pigments?
Yes—the 8°/d geometry and dual-aperture design minimize angular dependency artifacts, allowing repeatable assessment of goniochromatic materials when used with standardized positioning protocols.
Is spectral data export available for third-party analysis?
Yes—CQCS3 software exports full 400–700 nm reflectance spectra in CSV format, compatible with MATLAB, Python (NumPy/Pandas), and commercial color formulation platforms (X-Rite Color iMatch, Datacolor MatchText).
What calibration standards are supported?
Factory-calibrated against NIST-traceable white tile and BCRA Series II reference tiles; users may perform daily zero/white calibration using supplied physical white standard and built-in digital white reference.
Can measurement data be integrated into ERP or MES systems?
Via CQCS3’s ODBC-compliant database layer and configurable CSV export templates, enabling direct ingestion into SAP QM, Oracle Quality, or custom MES dashboards.
Is the device compliant with FDA or EU regulatory frameworks?
While not a medical device, its documentation package (including calibration certificate, uncertainty budget, and software validation summary) satisfies evidentiary requirements for ISO 13485 and IATF 16949 color-critical processes.
