Appearance measurement is a way of putting numbers to characteristics of surfaces that we see. The ability to independently quantify appearance allows for products to be similar whenever and wherever the product is manufactured or coated.
Increasingly specifications and standards require a physical assessment of gloss. Gloss measurement is necessary to monitor the uniformity, compatibility or possibly the deterioration of any protective gloss finish.
Gloss is measured by directing a constant intensity light beam at an angle to the test surface and monitoring the reflected light. Different surfaces require different reflective angles. 480 glossmeters cover the range necessary to measure any surface from high gloss to matt, providing a quantitative value to gloss measurement.
Each 480 Glossmeter is available in statistical versions, single, dual or triple angle geometry.
