Overview
The 3nh NS810 Portable Spectrophotometer is an ISO-compliant, LED-based spectrophotometric color measurement instrument engineered for precision, portability, and industrial robustness. It operates on the d/8° (diffuse/8°) optical geometry with a calibrated integrating sphere—ensuring uniform illumination and collection of reflected light from opaque, textured, or curved surfaces in accordance with CIE No. 15, ISO 7724-1, and ASTM E308 standards. The device employs a high-stability white LED source spanning the visible spectrum (400–700 nm) with spectral bandwidth optimized for CIE 1931 standard observer functions. Its core photometric architecture includes a grating-based monochromator and silicon photodiode array, enabling full-spectrum acquisition at 10 nm intervals. Designed for laboratory, production line, and field use, the NS810 delivers traceable CIELAB (L*, a*, b*) values, ΔE*ab, ΔE00, and chromaticity coordinates (x, y; u’, v’) with metrological consistency validated against NIST-traceable ceramic tile standards and ISO 13655 reference materials.
Key Features
- Portable form factor with integrated rechargeable battery (≥8 hours continuous operation) and ergonomic handheld design for on-site measurements across manufacturing floors, warehouses, and supplier audits.
- d/8° integrating sphere with matte white BaSO₄-coated interior ensures high diffuse reflectance uniformity (>98%) and minimizes directional bias per ISO 13655:2017 Annex A.
- LED illumination system provides stable spectral output over >50,000 cycles without warm-up delay or intensity drift—eliminating lamp replacement and reducing long-term calibration drift.
- ΔE*ab repeatability ≤ 0.04 under controlled ambient conditions (23 ± 2°C, RH 50 ± 5%), verified using 12-point intra-instrument reproducibility protocol per ISO 17991:2016.
- Onboard memory stores up to 2,000 spectral measurements with timestamp, operator ID, and sample tag—supporting GLP-compliant documentation workflows.
- Complies with CIE 15:2018, ISO/CIE 11664-4:2019 (CIELAB), and ASTM D2244 for color difference evaluation in quality control environments.
Sample Compatibility & Compliance
The NS810 accommodates flat, curved, granular, powder, liquid (with optional cell holder), and textured substrates—including painted metal, plastic injection-molded parts, textiles, ceramics, and printed packaging. Its 8 mm measuring aperture supports both single-point and multi-spot averaging modes. All optical components meet RoHS Directive 2011/65/EU and IEC 61000-4 electromagnetic compatibility requirements. Device firmware and calibration certificates are compliant with ISO/IEC 17025:2017 clause 6.4 (equipment verification) and support audit readiness for automotive (IATF 16949), pharmaceutical (USP ), and food packaging (ISO 22000) quality systems.
Software & Data Management
The NS810 interfaces via USB-C or Bluetooth 5.0 with SpectraMagic NX software (Windows/macOS), enabling full spectral data export (CSV, XML, CxF/X3), statistical process control (SPC) charting, tolerance setting (ellipsoidal ΔE00, rectangular L*a*b*), and batch comparison reports. Audit trail functionality logs all user actions—including calibration events, parameter changes, and result modifications—with time stamps and operator credentials, satisfying FDA 21 CFR Part 11 requirements when deployed with electronic signature validation. Cloud synchronization (optional) supports centralized database management across global R&D and QC sites.
Applications
- Automotive: Paint finish consistency verification across OEM body shops and Tier-1 suppliers (ASTM D2244 pass/fail thresholds).
- Plastics & Polymers: Batch-to-batch color matching for injection-molded housings, extruded profiles, and recycled resin blends.
- Printing & Packaging: Spot color verification (Pantone®, DIC, TOYO) and substrate metamerism assessment under multiple illuminants (D65, A, F2, UV).
- Textiles & Apparel: Shade sorting compliance with AATCC Evaluation Procedure 1 and ISO 105-J03 for dye lot acceptance.
- Food & Cosmetics: Color stability monitoring during shelf-life testing and raw material qualification (e.g., titanium dioxide dispersion in foundations).
FAQ
What calibration standards are supported?
The NS810 ships with a certified white ceramic calibration tile (L* = 94.5 ± 0.2, a* = −0.2 ± 0.1, b* = 1.8 ± 0.1) traceable to NIST SRM 2035. Optional secondary standards include black glass and green ceramic tiles for extended range verification.
Does the instrument support inter-instrument agreement (IIA)?
Yes—3nh provides IIA reports per ISO 13655:2017 Annex B, demonstrating mean inter-unit ΔE*ab ≤ 0.15 across five units measured on 20 standardized samples.
Can it measure translucent or transparent films?
With the optional transmission attachment and 10 mm path-length cuvette holder, the NS810 performs transmittance and Yxy analysis on clear films, bottles, and liquid solutions per ISO 11475.
Is firmware upgradeable in the field?
Yes—firmware updates are delivered via SpectraMagic NX and retain all user-defined tolerances, sample libraries, and calibration history without reset.
What is the recommended recalibration interval?
Annual recalibration is advised per ISO/IEC 17025:2017; however, daily verification using the supplied white tile is required prior to critical measurements.
