▸Description
The W-20b Webster Hardness Tester is a portable hardness testing instrument designed for fast, on-site inspection of aluminum alloys and other soft metals. Requiring only a simple clamping action, it delivers immediate hardness readings without the need for sample preparation, making it ideal for production, quality control, and field inspections.
Compliant with ASTM B647, the Webster Hardness Tester is widely used for evaluating the mechanical properties of aluminum profiles, tubes, sheets, extrusions, and fabricated components. It is particularly suited for rapid, non-destructive 100% inspection of finished products. Selected models are also available for testing brass, copper, and soft steel materials.
