EDDY CURRENT MATERIALS TESTING INSTRUMENT From the beginning, the name MAGNATEST has been considered as a synonym for reliable and highly sensitive materials testing. The eddy current magneto-inductive principle (which means working with a low frequency and a high field strength) used in the MAGNATEST with harmonic wave evaluation permits rapid, contactless testing of metal products for material properties (hardness, depth of hardness, alloy composition, heat treatment, etc.). The MAGNATEST family from FOERSTER offers you the entire range from the low-cost testing instrument for simple Yes/No sorting through to the high end instrument with multi-dimensional regression analysis.
