AELAB GM-247 Gloss Meter (Integral Type) for Multi-Angle Surface Gloss Measurement

The AELAB GM-247 Gloss Meter is an integral-type optical testing instrument developed for accurate and repeatable surface gloss measurement. The GM-247 model supports 20°, 45°, and 75° measuring angles, allowing comprehensive gloss evaluation across high, medium, and low gloss materials in laboratory and industrial environments.

Designed in accordance with international standards including ASTM D523, ASTM D1455, ASTM C346, ASTM C584, ASTM D2457, DIN EN ISO 2813, DIN 67530, EN ISO 7668, JIS Z8741, MFT 30064, TAPPI T480, GB 9754, GB/T 13891, GB 7706, and GB 8807, the AELAB GM-247 ensures consistent measurement accuracy and good repeatability. Its technical parameters conform to JJG 696-2002.

⚙️ Design & Construction

The AELAB GM-247 Gloss Meter features a compact integral structure with a stable optical path and precision-aligned measurement aperture. The handheld enclosure supports reliable positioning on test surfaces, while the backlit LCD ensures clear data visualization under low-light laboratory or production conditions.

🔬 Working Principle / Testing Method

The AELAB GM-247 analyzes surface gloss by projecting light onto a material surface at fixed geometrical angles of 20°, 45°, or 75°. The reflected light intensity is quantified and converted into gloss units, enabling objective comparison of surface finish, coating uniformity, and material reflectivity.
