Product Description
The W-B75/B Series Webster Hardness Tester is a compact and portable one-hand-operated instrument designed for rapid on-site hardness testing of soft brass and similar materials. With a simple clamping action, hardness values can be obtained instantly without damaging the surface of the workpiece. Standard hardness blocks included with the instrument are verified through certified hardness machines to ensure accuracy and stability. The measured Webster hardness values can be converted into commonly used hardness scales such as Rockwell, Vickers, Brinell, as well as tensile strength data. This makes the W-B75/B series highly suitable for production inspection, acceptance inspection, and field quality supervision.
Product Advantages
Well-suited for quick, non-destructive hardness testing of profiles, tubes, and plates, especially in production, sales, and construction environments.
Equipped with a certified standard hardness block to ensure reliable daily calibration and measurement accuracy.
Webster hardness values can be converted into Rockwell, Vickers, Brinell hardness and tensile strength for comprehensive material evaluation.
Application Range
Determine whether a workpiece has undergone heat treatment
