Dye penetrant (DP) testing, often referred to as a fluorescent penetrant inspections (FPI), is an important method of nondestructive testing of materials that occurs when a fluorescent dye is applied to a non-porous material surface to detect micro-fractures, delamination, seams and other defects with an ultraviolet light. ViewTech Borescopes is debuting the VJ-3 Ultraviolet (UV) video borescope which facilitates endoscopic dye penetrant testing by detecting internal and external surface defects. These insp
