Gloss is a surface's attribute of directly reflecting light and the degree of this reflected light is termed glossiness. The IG-320 measurement angle is set at the 60° standard angle allowing discerning even the lowest levels of gloss and provides a definite numerical value for glossiness. The IG-320 provides accurately and instantaneously measurement from low gloss matte surfaces to the highly polished texture for such operations management areas as floor maintenance, polishing, and coating. Up to 99 measurements can be taken with a simple key operation and averaged using another key. Up to 99 averages can be stored for later use. Easy data management promises smooth inspection work. Because the IG-320 does not require the use of special measuring technology, it can easily be used by anyone.
