Abstract
Apparatus for testing hardness properties of materials may comprise: a clamping assembly including a housing in which is carried a magnet for magnetically attaching the apparatus to the material being tested and a head assembly having a penetrator member mounted for engagement with said material being tested and for limited axial movement from a first position to a second position; an actuator connected to the penetrator member for applying predetermined loads thereto; and an indicator responsive to axial movement of the penetrator member to measure the hardness of the material.
