The UH4000 Series universal hardness tester comes in two key configurations: UH4250 (hardness scale 0.5-250 kgf) and UH4750 (hardness scale 3-750 kgf). The Wilson UH4000 tests Rockwell, Vickers, Knoop and Brinell hardness scales within the selected tester load range. Its sturdy design will withstand the toughest production environments. The tester features a closed loop loading cycle for best accuracy, and faster testing cycles, and it includes a new eight-position turret to hold a desired combination of indenters and objectives. It has a large 300-mm x 400-mm T-slot stage with high weight capacity, enabling the testing of heavy and large parts nondestructively. An optional clamping tool is available to ensure stability during the test process; both manual and automatic stage movement options are also available. The UH4000 is suitable for testing large components such as castings and forgings, flat or cylindrical workpieces, steels and heat-treated materials.
