Overview
The 3nh YG60S 60° Single-Angle Gloss Meter is a precision optical instrument engineered for reliable, repeatable measurement of specular gloss at the standardized 60° geometry. It operates on the principle of measuring the ratio of reflected luminous flux from a test surface to that from a calibrated black glass reference standard (with refractive index n = 1.567), under controlled illumination conditions defined by ISO 2813 and ASTM D523. Designed for routine quality control in industrial manufacturing environments, the YG60S delivers traceable gloss readings in gloss units (GU) with high short-term repeatability—critical for process validation and material consistency verification. Its fixed 60° angle configuration targets mid-gloss surfaces (typically 10–70 GU), making it especially suitable for coatings, plastics, and laminated substrates where moderate reflectivity dominates. The instrument’s optical architecture includes a stabilized LED light source, precision collimated optics, and a silicon photodiode detector aligned per CIE illuminant D65 spectral distribution, ensuring compliance with international metrological requirements for working gloss meters per JJG 696.
Key Features
- Single-angle 60° optical configuration optimized for mid-gloss measurement per ISO 2813 and ASTM D523
- Integrated automatic power-off function to conserve battery life during idle periods
- Ergonomic curved housing designed for one-handed operation and stable positioning on curved or planar surfaces
- High-stability LED light source with minimal thermal drift over extended measurement sessions
- Calibration traceable to national standards via factory-certified black glass reference tile (n = 1.567)
- Compact, portable form factor with integrated display and intuitive button interface for field and lab use
Sample Compatibility & Compliance
The YG60S accommodates flat, slightly curved, or textured non-metallic surfaces including painted panels, printed films, molded plastic housings, ceramic tiles, and coated metallic substrates. It is not intended for highly absorptive, translucent, or anisotropic materials requiring multi-angle or directional scattering analysis. The instrument meets the performance criteria for Working Gloss Meters specified in JJG 696–2015 (Chinese National Verification Regulation), and its optical design conforms to the geometric and photometric requirements of ISO 2813:2014 and ASTM D523–14. While primarily a gloss meter, the YG60S also incorporates dual-function capability for haze and transmittance measurement on transparent or semi-transparent sheet materials (e.g., PET films, acrylic sheets, polycarbonate glazing), supporting basic optical quality screening in inline QC workflows.
Software & Data Management
The YG60S operates as a standalone instrument with onboard data storage for up to 200 measurement records. It supports USB-C connectivity for direct data export to Windows-based PCs using 3nh’s proprietary PC software (compatible with Windows 10/11). The software enables statistical analysis (mean, max/min, standard deviation), batch report generation in PDF/CSV formats, and user-defined pass/fail thresholds aligned with internal specification limits. Audit trail functionality includes timestamped measurement logs, operator ID tagging (via manual entry), and calibration history tracking—supporting GLP-aligned documentation practices. Although not FDA 21 CFR Part 11 compliant out-of-the-box, the system can be validated for regulated environments when deployed with documented SOPs and periodic verification against certified reference standards.
Applications
- Coatings & Inks: Monitoring gloss uniformity across spray-applied automotive clearcoats, coil-coated metal, and gravure-printed packaging films
- Plastics & Electronics: Verifying surface finish consistency of injection-molded housings, touch panel overlays, and backlit membrane switches
- Paper & Printing: Assessing varnish gloss levels on commercial offset prints, laminated labels, and premium packaging substrates
- Building Materials: Evaluating glaze uniformity on porcelain tiles, polished marble slabs, and architectural aluminum extrusions
- Automotive Interiors: Controlling gloss match between dashboards, door trims, and center consoles during assembly line QA
FAQ
What is the measurement geometry of the YG60S?
The YG60S uses a fixed 60° incident/reflectance angle configuration per ISO 2813, optimized for mid-gloss surfaces.
Does the YG60S require annual recalibration?
Yes—routine recalibration against the supplied black glass standard is recommended every 12 months or after 5,000 measurements, whichever occurs first, to maintain traceability.
Can the YG60S measure metallic or brushed finishes?
It can measure gloss on metallic paints and PVD-coated surfaces, but results may vary with orientation on directional finishes; ISO 2813 specifies measurement on representative areas with consistent orientation.
Is haze measurement performed using the same optical path as gloss?
No—haze and transmittance are measured using a separate collimated beam path through the sample, following ASTM D1003 principles, with independent detector alignment.
What environmental conditions affect measurement accuracy?
Ambient temperature fluctuations exceeding ±5°C from calibration temperature (23±2°C) and relative humidity above 80% RH may impact repeatability; operation within ISO 291 standard climate is advised.
