Visual Testing (VT)

Visual testing is the observation of a test object or specimen, either directly with the eyes, or indirectly by utilizing optical instruments, by an inspector or technician to evaluate the presence of surface anomalies, or an object’s conformance to a specification.

Visual examination is the most basic non-destructive testing method, which precedes and is used in conjunction with any others NDT method. Visual inspection is a method that ranges from simply looking at a part to see if surface imperfections or defects are present and visible, to using video inspection systems and small diameter bore scopes to reach into areas with limited access.

The portable video scopes combine light weight with reliability and ease of use with advanced features to allow inspections in various positions and conditions.
