Concrete Test Hammer SADT HT-225A

Description HT-225A is used for testing the strength of various concrete members ( slab, beam, column, truss) of normal building strength and bridge. The HT 225A is comparable with the Schmidt Hammer, Type N, this method of testing is covered by DIN 1048 and BS1881 part 202, referring to assessment of the rebound hardness of mortar which is directly related to the compressive strengths of the tested material.
