AELAB GM-268 20°/60°/85° Gloss Meter for Multi-Angle Surface Gloss Measurement

The AELAB GM-268 20°/60°/85° Gloss Meter performs quantitative surface gloss measurement for coatings, printed materials, plastics, ceramics, stone, and metallic finishes. The GM-268 is engineered for repeatable gloss testing in laboratory analysis, industrial inspection, and production quality control environments, ensuring stable results for surface appearance evaluation.

The AELAB GM-268 Gloss Meter follows international gloss measurement standards including ASTM D523, ASTM D1455, ASTM C346, ASTM C584, ASTM D2457, DIN EN ISO 2813, DIN 67530, EN ISO 7668, JIS Z8741, and GB/T 13891. The GM-268 supports fast gloss assessment, auto calibration, data storage up to 254 groups, and an easy-to-read 4-digit backlit LCD for low-light operation.

⚙️ Design & Construction

The AELAB GM-268 is a compact, integral-type gloss meter designed for portable surface gloss measurement. The GM-268 integrates multi-angle measurement geometry (20°/60°/85°) and an elliptical measuring area of 7 mm × 14 mm to stabilize gloss readings across curved, flat, and coated surfaces. A 4-digit backlit LCD improves measurement visibility, while the durable handheld form supports routine field inspection and laboratory QA workflows.

🔬 Working Principle / Testing Method

The AELAB GM-268 Gloss Meter quantifies gloss units (GU) by projecting a controlled light source at fixed incident angles of 20°, 60°, and 85°, then measuring the reflected intensity from the test surface. The GM-268 calculates gloss based on the reflection ratio relative to calibration standards, enabling reliable comparison of coating quality, surface cleanliness, and material finish consistency. Auto calibration maintains measurement stability and supports repeatability of ±0.5 GU across repeated tests.
