The LMI Ripple Gauge was designed to be a high accuracy surface profiling gauge which was originally developed for Boeing to measure ripples in the outer skin of aircraft. Capturing surface contour data is now possible in order to find and record any imperfections no matter how small.

The unit sits on three datum feet to accommodate even curved surfaces and is secured in place with suction cups. The suction cups provide stability for accurate measurements while also allowing the user to record data at any orientation. The gauge connects to a laptop USB port or ASI Datamyte’s rugged 4000 tablet PC and the (X, Y) pairs can be viewed live on the screen.
