Left unchecked corrosion can impede performance and can lead to component failure, sometimes with catastrophic results. Inspectors must be able to accurately determine corrosion severity to ensure part performance. But visual inspection is very open to interpretation, and high resolution, quantitative metrology systems are too expensive, too susceptible to vibration, and too size limited for shop use.

The 4D InSpec Surface Gauge instantaneously measure pit depth, width and volume, of all corrosion pits within the field of view. Quickly inspect corrosion over large portions of a component for a thorough, accurate assessment of the severity, even in difficult to access areas such as corners, bores and fillets.
