Overview
The 3nh HG60S Single-Angle 60° Gloss Meter is a precision optical instrument engineered for rapid, repeatable surface gloss evaluation in quality control and R&D environments. It operates on the principle of specular reflectance measurement at a fixed incident angle of 60°, in accordance with ISO 2813, ASTM D523, and GB/T 9754 standards. This geometry is optimized for medium-gloss surfaces—such as painted automotive panels, coated plastics, laminated wood finishes, and printed packaging—where reflectance values typically fall within the 10–100 GU range. The device employs a CIE-standard illuminant C light source and conforms to the CIE 1931 2° standard observer function, ensuring metrological traceability and inter-laboratory comparability. Its compact, handheld architecture integrates a high-stability photodetector array and temperature-compensated optical path, minimizing drift across ambient operating conditions (0–40 °C). With a measurement cycle of just 0.5 seconds and automatic zero calibration upon startup, the HG60S supports high-throughput inspection without sacrificing accuracy or repeatability.
Key Features
- Single-angle 60° configuration optimized for routine QC of industrial coatings, films, and molded parts
- High-resolution 3.5-inch TFT color display (320 × 480) with intuitive icon-based UI supporting both English and Simplified Chinese
- Robust optical design featuring CIE C illuminant and CIE 1931 2° photopic response for standardized gloss quantification
- Calibration traceable to national standards via included certified gloss reference plate (typically 100 GU ± 0.5 GU)
- Integrated rechargeable 3.7 V / 3200 mAh lithium-ion battery enabling >5000 measurements per full charge
- Dual communication interfaces (USB and RS-232) for seamless integration into LIMS or SPC systems
- Compact ergonomic housing (160 × 75 × 90 mm) weighing only ~350 g—ideal for field use and benchtop deployment
Sample Compatibility & Compliance
The HG60S is designed for flat or gently curved non-metallic surfaces with minimal texture variation. It accommodates substrates including but not limited to: solvent- and water-based paints, powder coatings, PET and PC films, laminated paperboard, anodized aluminum, and ceramic glazes. Surface curvature radius should exceed 200 mm to maintain optical alignment integrity. The instrument complies with JJG 698–2009 “Verification Regulation for Working Gloss Meters” (Class II), satisfying metrological requirements for in-house calibration verification. While not intrinsically compliant with FDA 21 CFR Part 11, its data export capability (via timestamped CSV files over USB/RS-232) supports GLP/GMP-aligned documentation workflows when paired with validated laboratory software.
Software & Data Management
The HG60S supports bidirectional serial communication protocols for real-time data streaming and batch export. When connected to a host PC, users may log sequential measurements—including date/time stamps, sample IDs, and operator codes—using third-party SPC or Excel-based templates. Firmware updates are delivered via USB mass storage mode. Although the meter lacks onboard data analysis tools, its consistent output format (GU value + metadata) enables direct import into statistical process control platforms such as Minitab, JMP, or custom Python/Pandas pipelines. Optional micro-printer support allows on-site hardcopy generation of measurement records for audit trails.
Applications
- Automotive OEM and Tier-1 suppliers verifying paint gloss uniformity across body panels
- Plastics converters validating extrusion and thermoforming surface finish consistency
- Printing and packaging facilities monitoring varnish and lamination gloss retention
- Architectural coating labs assessing weathering-induced gloss loss per ISO 2813–2014
- Academic materials science labs correlating surface roughness (measured via AFM) with 60° gloss response
- Quality assurance teams performing incoming inspection of coated metal or glass components
FAQ
What standards does the HG60S comply with?
It meets JJG 698–2009 Class II requirements and is configured per ISO 2813 and ASTM D523 for 60° geometry.
Can the HG60S measure curved surfaces?
It is suitable for gently curved surfaces with radius ≥200 mm; tighter curvatures require multi-angle instruments (e.g., 20°/60°/85° triple-angle models).
Is calibration certificate included?
A factory-calibrated reference standard plate is supplied; NIST-traceable calibration certificates are available as optional add-ons.
Does it support data export for regulatory audits?
Yes—measurements can be exported via USB or RS-232 in plain-text CSV format, enabling integration into validated electronic record systems.
How often should the instrument be recalibrated?
Annual verification against certified standards is recommended; daily zero-check using the provided black trap is advised before critical measurements.
