W-B75 Web Hardness Tester

Name: W-B75 Web Hardness Tester
Brand: Beijing Lanetech Square Co., Ltd.

The W-B75 brass alloy Webster hardness tester is specifically designed for rapid hardness testing of brass alloys directly on the production floor. Its operation is straightforward: the sample is positioned between the anvil and the indenter, and pressure is applied to the handles until a “bottom” sensation indicates it’s time to read the dial indicator. This device emphasizes high efficiency and reliability, adhering to the Chinese non-ferrous standard YS/T471-2000.

As the instrument of choice for assessing the strength of brass alloys, the W-B75 is capable of measuring the hardness of brass alloy pipes and plates. It is particularly valuable for conducting swift, non-destructive tests piece by piece in environments of mass production and sales, ensuring each brass alloy component meets quality standards.
