Effortlessly perform corrosion mapping with a variety of automated raster arms solutions.

The NAVIC, in conjunction with the motorized raster arm, is engineered to assist in the identification of variations in material thickness due to corrosion. The NAVIC - Corrosion Mapping Scanner will follow specific scan paths which are programmed using the remote handheld controller. Perform precision c-scans, line scans, HydroFORM and more using the wide variety probe holders available.
