Leeb Hardness Tester for Metal Steel Electric Leeb Hardness Tester for Metal Steel
Digital Leeb hardness tester is developed Leeb hardness measurement principle based on the internationally popular metal material hardness tester. It has high accuracy, small size, easy to operate, and a wide range of measurement, especially for large, heavy-duty malleable pieces, example: roll turbine shaft, and applied to the components already installed and can not be demolished, for example, site hardness testing of pressure vessels, turbine units and other equipment. Leeb hardness tester is widely used in petrochemical, aerospace, electric power, gas, automotive, shipbuilding, railways, machinery manufacturing and other industries.
