ABSTRACT:
A support for a hardness testing device, the support being capable of positioning the hardness testing device to measure hardness of a surface in different positions. The multipositionable support comprises a pair of elongted parallel support members along which is supported a slidably adjustable cross-beam member for positioning a hardness device relative to a surface being tested. Each support member has pivotally connected to one of its ends a magnetic means which may be moved about its pivotal axis and rotated about the axis of its support member for alignment of the magnet means with an adjacent supporting surface. The magnet means has sufficient holding power to fixedly and rigidly hold the support against the force applied to the indentor of the testing device. The hardness testing device is coupled to an actuator knob at the cross-beam and is supported at the cross-beam.
