3nh NR10QC Portable Color Difference Meter (Economy Model)

Overview

The 3nh NR10QC Portable Color Difference Meter is an entry-level, high-repeatability spectrophotometric color measurement instrument engineered for routine color quality assurance in production and laboratory environments. It operates on the CIE 1976 L*a*b* color space and conforms to fundamental photometric principles defined by the International Commission on Illumination (CIE), as well as relevant national standards (e.g., GB/T 3978–2008, GB/T 3979–2008). The device employs an 8°/diffuse optical geometry—compliant with ISO 7724-1 and ASTM E308—ensuring robust measurement of both matte and moderately textured surfaces without specular component exclusion (SPIN mode). Its D65 illuminant simulation aligns with daylight conditions at correlated color temperature of 6504 K, enabling consistent inter-instrument and cross-laboratory color evaluation. Designed for operational simplicity and field-deployable reliability, the NR10QC delivers metrologically traceable color difference data (ΔL*, Δa*, Δb*, ΔE*ab) without dependency on external computing hardware.

Key Features

• High short-term repeatability: ΔE*ab < 0.03 under controlled ambient conditions—validated per ISO 13655:2017 for intra-unit stability across repeated measurements on uniform targets.
• Dual visual alignment system: Integrated crosshair reticle and concentric illumination ring ensure precise positioning over small or irregular sample areas, minimizing edge effects and operator-induced variability.
• Fixed 4 mm aperture: Optimized for localized spot measurement in textiles, coatings, plastics, and printed materials where spatial resolution is critical.
• Integrated rechargeable lithium-ion battery: Supports >5,000 consecutive measurements per full charge; battery status indicator enables proactive power management during extended QC shifts.
• Self-contained calibration architecture: Factory-stored white reference values eliminate need for daily white/black tile recalibration—reducing setup time and mitigating drift from frequent physical standard handling.
• Standalone operation: No PC connection required for power-on, measurement, or basic pass/fail judgment—ideal for inline inspection stations with constrained IT infrastructure.
• Ergonomic handheld form factor: Weight-balanced chassis with non-slip grip facilitates one-handed use across diverse industrial settings, including fabric rolls, molded parts, and packaged goods.

Sample Compatibility & Compliance

The NR10QC accommodates flat, curved, and slightly textured surfaces typical of textile swatches, painted metal panels, injection-molded plastic housings, coated paper, and food packaging films. Its 8°/diffuse configuration provides stable readings on non-Lambertian materials, though highly glossy or mirror-finished substrates require careful orientation to minimize specular reflection influence. The instrument meets electromagnetic compatibility requirements per GB/T 18268.1–2010 (equivalent to IEC 61326-1) and environmental operating specifications (10–40 °C, RH ≤ 85% non-condensing). While not certified to FDA 21 CFR Part 11 or ISO/IEC 17025, its measurement traceability supports internal GLP-aligned documentation workflows when used with standardized SOPs and periodic verification using NIST-traceable ceramic tiles.

Software & Data Management

Data export is supported via USB-C interface to standard CSV format for integration into existing LIMS or ERP systems. Optional 3nh ColorManager Basic software (Windows-compatible) enables batch reporting, tolerance zone definition (ellipsoidal or rectangular ΔE limits), statistical process control (SPC) charting (X-bar/R), and historical trend analysis. Audit trail functionality includes timestamped measurement logs with operator ID fields—facilitating basic compliance with internal QA protocols. No cloud synchronization or remote firmware updates are implemented, preserving data sovereignty and network security in regulated manufacturing zones.

Applications

The NR10QC serves as a primary color verification tool across vertically integrated supply chains: textile dye houses monitor batch-to-batch shade consistency against master standards; automotive trim suppliers validate interior component color match under D65 lighting; pharmaceutical blister packaging lines verify inkjet-printed lot codes for hue fidelity; and food manufacturers assess natural pigment variation in fruit-based fillings or confectionery coatings. Its portability enables rapid line checks at receiving docks, production cells, and warehouse staging areas—reducing reliance on centralized lab instruments for first-pass conformance screening.

FAQ

Is the NR10QC suitable for measuring metallic or pearlescent finishes?

No—its 8°/diffuse geometry does not support multi-angle measurement required for gonioapparent materials. Use dedicated goniospectrophotometers (e.g., BYK-mac or X-Rite MA98) for such applications.
Does the device support CMC or ΔE00 color difference formulas?

No—it calculates only CIE ΔE*ab (1976) and individual L*, a*, b* coordinates. Advanced metrics require post-processing in third-party software.
Can the instrument be recalibrated by the user?

No—white calibration is factory-fixed and non-adjustable. Users must rely on supplied ceramic calibration tile for periodic verification; field recalibration is not supported.
What is the recommended verification frequency?

Perform verification against the included calibration tile at start/end of each shift, or before any critical measurement campaign, per internal QA procedure.
Is firmware upgrade capability available?

Firmware updates are provided exclusively via 3nh technical support upon request and require Windows-based utility software—not accessible through the device UI.
