Overview
The 3nh Colorimeter HI is a high-precision, portable spectrophotometric color difference meter engineered for rapid, repeatable, and traceable color measurement in industrial quality control environments. It operates on the d/8° integrating sphere optical geometry—compliant with ISO 7724-1, CIE No. 15, and ASTM E308—ensuring uniform illumination and diffuse viewing conditions ideal for measuring textured, glossy, or matte surfaces without directional bias. Its solid-state LED light source delivers stable spectral output across the visible range (400–700 nm), eliminating lamp aging drift and enabling consistent inter-instrument agreement. Designed specifically for field-deployable use in production lines, R&D labs, and supplier audits, the Colorimeter HI bridges laboratory-grade accuracy with handheld convenience—supporting real-time decision-making where color consistency directly impacts product acceptance, brand integrity, and regulatory compliance.
Key Features
- Integrated d/8° integrating sphere with dual-beam optical path design to minimize stray light and enhance signal-to-noise ratio
- High-stability LED illuminant with spectral power distribution optimized for CIE standard illuminants D65 and A
- Dedicated “Smart Button” interface enabling one-touch operation for calibration, measurement, and data recall without external devices
- Non-contact automatic white calibration—performed in under 3 seconds using built-in reference tile detection algorithm
- Bluetooth 5.0 wireless connectivity for seamless pairing with iOS and Android devices
- On-device memory storing up to 1,000 measurement records with timestamp, operator ID, and sample name metadata
- Rugged IP52-rated enclosure with rubberized grip and scratch-resistant sapphire window for extended field durability
Sample Compatibility & Compliance
The Colorimeter HI accommodates flat, curved, and slightly textured substrates—including ceramic grout joints, painted metal panels, textile swatches, plastic housings, and coated tiles—without requiring physical contact or sample preparation. Its 8 mm measurement aperture ensures representative averaging over heterogeneous surfaces common in grout, sealant, and architectural coating applications. The instrument conforms to international colorimetric standards including ISO 11664 (CIE colorimetry), ISO 17972-1 (digital color communication), and GB/T 3979–2008 (Chinese national standard for colorimeters). Measurement data meets GLP documentation requirements when used with audit-trail-enabled software modules; full traceability is maintained via embedded firmware timestamps and encrypted export logs.
Software & Data Management
Paired with the official 3nh ColorCloud mobile application (iOS/Android) and WeChat Mini Program, the Colorimeter HI enables cloud-based color database management, spectral data sharing, and cross-location team collaboration. The app supports CIE L*a*b*, L*C*h*, ΔE*ab, ΔE00, and Yxy color spaces, with customizable tolerances per product line. Integration with 3nh’s ColorMatching Cloud platform allows formulation support for tile grout, epoxy resin, and polymer-based sealants—leveraging spectral reflectance curves rather than tristimulus approximations for higher prediction fidelity. All exported reports include instrument serial number, calibration date, observer angle (10°), and illuminant metadata—ensuring compliance with internal QA protocols and external customer audit requests.
Applications
- Quality assurance of ceramic tile grout color consistency during installation and post-curing inspection
- In-line color verification of automotive interior trim, consumer electronics housings, and appliance finishes
- Batch-to-batch comparison of architectural coatings, waterborne paints, and UV-curable inks
- Textile dye lot validation across woven, knitted, and nonwoven substrates under controlled ambient lighting
- Color matching support for R&D teams developing custom grout formulations with pigment dispersion optimization
- Supplier qualification audits requiring objective, instrument-based pass/fail criteria aligned with brand color standards
FAQ
What is the recommended calibration frequency for routine production use?
For continuous daily operation, perform white calibration before each measurement session and full dark/white calibration weekly—or after any significant ambient temperature shift (>5°C).
Does the Colorimeter HI support third-party color management systems (e.g., X-Rite Color iMatch or Datacolor Match Pigment)?
Yes—spectral data (31-point reflectance values at 10 nm intervals) can be exported as .csv or .qtx files compatible with major formulation software platforms.
Can measurements be performed under ambient lighting without a dark enclosure?
Yes—the integrated sphere design and LED illumination ensure stable readings under typical indoor lighting (≤ 500 lux); however, direct sunlight or flickering fluorescent sources should be avoided.
Is firmware update capability available over-the-air via Bluetooth?
Yes—firmware updates are delivered through the ColorCloud app and applied automatically upon device pairing and confirmation.
How is measurement uncertainty quantified and documented for ISO/IEC 17025-compliant laboratories?
Uncertainty budgets follow EURACHEM/CITAC Guide CG4 methodology, incorporating repeatability, inter-instrument variation, calibration standard uncertainty, and environmental influence factors—all accessible in the instrument’s diagnostic report mode.
