KNES has a multi-functional system for tube inspection to detect wall thinning by using Eddy Current Testing. Its combined applications cover inspection of all kinds of condensers and heat exchanger units. The system makes it easy to detect corrosion, pitting and surface cracks in any type of materials.

Eddy-current testing is one of many electromagnetic testing methods used in nondestructive testing making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials. Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.
