Orange Peel / DOI Meters

Total Appearance Measurement

How to characterize a perfect finish? Paint appearance is described by its brilliance and smoothness, often referred to as DOI (Distinctness of Image) and Orange Peel. For years the BYK-Gardner orange peel and DOI meters have been used at all major car makers and suppliers as the global standard to objectively control and optimize appearance. The wave-scan family offers tailored appearance measurement solutions for every task, from portable units for the painted body or small add-on parts, to a robotic sensor for automatic appearance measurement.
