Hardness Testing is a critical NDT method used to determine the structural integrity, wear resistance, and heat-treatment success of metal components. By measuring a material’s resistance to localized plastic deformation, technicians can estimate tensile strength and verify that parts meet specific engineering requirements. This category features a range of Portable Hardness Testers, including UCI (Ultrasonic Contact Impedance) and Leeb Rebound units, designed for high-precision field use on large or fixed assets. Whether you are inspecting heat-affected zones (HAZ) in welds, verifying engine components, or testing heavy castings, our selection of hardness testers provides the accuracy of a laboratory in a rugged, handheld format.
