The DuraRock 130 & 250 are accurate, durable, and reliable hardness testers with many features and benefits such as test surface referencing, clamping capability, and speed.
The Nose Piece serves as a reference point during testing to compensate for any deformation of the machine or the test piece that would otherwise effect the result. This reduces operator error and provides consistent and accurate results with minimal test piece preparation and operator training.
The Clamping Shield allows testing of large parts without external support by securing the piece before testing. The Clamping Shield also protects the diamonds from breakage by impact.
Test times as low as 4 seconds increases efficiency in the lab as the preload and load are applied through one pull of a lever.
