Overview
The 3nh PSY02 is a portable, spectrophotometric color difference meter engineered for high-precision, non-contact color measurement in industrial quality control environments. It operates on the d/8° integrating sphere geometry—standardized under CIE No. 15 and ISO 7724-1—to ensure uniform illumination and diffuse reflectance collection, minimizing directional bias and enhancing inter-instrument agreement. Unlike tristimulus colorimeters, the PSY02 captures full spectral reflectance data across the visible spectrum (400–700 nm) using a high-stability LED light source and a precision silicon photodiode array. This enables calculation of CIELAB (L*a*b*), CMC, DIN99, and other industry-standard color difference metrics with repeatability of ΔE*ab ≤ 0.045—meeting stringent requirements for batch-to-batch consistency in architectural coatings, tile grout formulation, ceramic glaze verification, and polymer surface finishing.
Key Features
- Integrated d/8° optical architecture with matte white PTFE-coated integrating sphere for stable, geometry-compliant measurements
- Dual-mode operation: standalone handheld measurement and smartphone-connected cloud workflow via Bluetooth 5.0
- “Smart Button” interface with context-aware function mapping—enabling one-touch white calibration, sample capture, and pass/fail threshold evaluation
- Non-contact auto-calibration using certified reference white tile—eliminating manual alignment errors and reducing operator dependency
- Real-time spectral data export (CSV, XML) supporting traceable calibration history and audit-ready records
- Rugged IP54-rated enclosure with rubberized grip and drop-resistant design (1.2 m height rating), optimized for factory floor and on-site tile installation environments
Sample Compatibility & Compliance
The PSY02 accommodates flat, curved, textured, and glossy surfaces—including ceramic tiles, porcelain slabs, epoxy grouts, UV-cured sealants, and cementitious joint compounds—without requiring physical contact or sample preparation. Its 8 mm measurement aperture ensures representative averaging over micro-textures common in floor and wall surfacing materials. The instrument conforms to international colorimetric standards including ISO 7724-1 (instrumental color measurement), ASTM E308 (computation of color coordinates from spectral data), and GB/T 3978–2008 (Chinese national standard for colorimetry). All firmware and calibration routines are designed to support GLP-compliant workflows, with optional timestamped calibration logs and user-accessible traceability reports required for ISO 9001-certified manufacturing audits.
Software & Data Management
The PSY02 interfaces natively with the 3nh “ColorCloud” ecosystem—comprising iOS/Android apps and web-based SaaS modules—enabling real-time spectral database synchronization, cross-location color matching, and formulation assistance for tile grout and decorative mortar systems. Measurement data is encrypted during Bluetooth transmission and stored with immutable metadata (operator ID, GPS-tagged location, ambient illuminant ID, device serial number). The platform supports FDA 21 CFR Part 11–aligned electronic signatures, audit trails, and role-based access control—essential for regulated construction material suppliers serving commercial and healthcare facility projects. Export formats include CxF/XRGA for integration with major paint formulation software (e.g., BYK-Gardner LabSoft, Datacolor Match Textile).
Applications
- On-site verification of grout color consistency across large-scale tiling installations (e.g., hospitals, airports, metro stations)
- Rapid qualification of batch-mixed epoxy or polyurethane joint compounds against master standards
- Quality gate inspection of glazed ceramic tiles and porcelain panels prior to packaging
- Color deviation analysis in UV-curable surface sealants applied over natural stone or concrete substrates
- Development and validation of custom color palettes for architectural pre-finished wall systems
- Supplier qualification audits where spectral agreement (not just ΔE) between source and target is contractually mandated
FAQ
Does the PSY02 require annual factory recalibration?
No—its LED-based optical system exhibits negligible drift; however, quarterly verification against NIST-traceable ceramic white tiles is recommended per ISO/IEC 17025 guidelines.
Can it measure translucent or highly specular grout materials?
Yes—the d/8° sphere geometry with specular component excluded (SCI mode) mitigates gloss interference; users may toggle between SCI and SCE modes depending on surface finish requirements.
Is spectral data accessible for third-party analysis?
Yes—raw 10-nm interval reflectance spectra (31 points) are exportable via USB-C or Bluetooth for offline analysis in MATLAB, Python (NumPy/SciPy), or proprietary color science toolchains.
How does the “ColorCloud” platform support multi-site color management?
Each registered PSY02 uploads time-stamped spectral data to a centralized tenant-specific cloud instance, enabling comparative analytics across geographically dispersed production lines or contractor teams.
Does the device comply with EU RoHS and REACH directives?
Yes—all electronic components and housing materials meet RoHS 2011/65/EU and REACH SVHC screening thresholds, with full declarations available upon request.
