HARDNESS TESTING (HT) is today one of the most frequently employed methods for mechanical material testing, in particular for metals. On the one hand, this test method allows qualitative relationships to other material properties (e.g. strength, rigidity, density) or to the behavior of the materials under certain loads (e.g. wear resistance) to be established. Hardness testing of metals is frequently required by specifications to help determine properties such as abrasive resistance, brittleness, ductility, yield and tensile strength.
The hardness test is comparatively quick and simple to perform and causes relatively little damage to the specimen, i.e. only very minor marks are left on the specimen surface. It also provides a simple method for quality control (incoming goods and outgoing goods inspection). The hardness test method also allows a wide variety of geometries to be tested.
Our hardness methods include: Barcol Hardness,Leeb Hardness,Vicker hardness and Ultrasonic Contact Impedance (UCI) hardnes.

REMOTE FIELD TESTING (RFET) is an electromagnetic examination, which utilizes a through-transmission process. The resultant field is affected by either ID or OD tube wall anomalies. RFT signal measurements are made a few tube diameters away from the excitation coil without any attempt at tube wall magnetization or saturation. A pair of pick-up coils located in the remote field zone measures the resultant field to give both a differential and an absolute signal. The signal phase and amplitude information are used to determine defect depth and volume.
