We can provide steel or austenitic calibration test blocks, standard size blocks or custom specified geometries with added reflectors e.g. side drilled holes or notches. These blocks can normally be used for sound frequencies up to 10MHz, but we also provide very fine-grained steel that which can be used for sound frequencies up to 50MHz (ASTM Grain Size nr.11).
All calibration test blocks are ultrasonically tested and include traceable certification documentation.
