Novo-Gloss 20/60/75ºS gloss meter

Product catalog summary

Introduction
The Rhopoint Instruments Limited introduces the Novo-Gloss 20/60/75 Glossmeter, a fully featured instrument designed for measuring the gloss of various substrates. Gloss is a critical aspect of visual perception, influencing the psychological impact of products on consumers. It is defined as the attribute of surfaces that gives them a shiny or lustrous appearance.

Importance of Measuring Gloss
Gloss measurement is essential for ensuring consistent product appeal, such as in reflective car body panels or glossy magazine covers. ASTM D523 outlines three measurement angles (20°, 60°, and 75°) to measure gloss across all surfaces. Gloss is measured in gloss units (GU) and is traceable to standards in Germany, Canada, and the UK.

Measurement Angles

Universal Measurement Angle (60°): Suitable for all gloss levels and used as a reference angle.
Low Gloss (75°): Used for improved resolution of low gloss, particularly for paper, with a larger measurement spot.
High Gloss (20°): Provides improved resolution for high gloss surfaces and is sensitive to haze effects.

Gloss Measurement Process
Gloss is measured by shining a known amount of light at a surface and quantifying the reflectance. The angle and method depend on the surface and the aspect of appearance being measured.

Sample Applications
Gloss measurement is applicable to materials such as paper, ink, and paint.
