Advantages and disadvantages of Shandong portable Leeb hardness tester

The portable Leeb hardness tester is a portable hardness tester used to check the hardness of large workpieces on site. Its main advantages and disadvantages are as follows:

Advantages: easy to carry and use, and can be carried to the site for rapid hardness measurement of large workpieces. It can also be converted into other hardness values, such as Brinell, Rockwell, Vickers, and Shore. It is a hardness testing equipment that is very useful for on-site testing.

Disadvantages: The error is larger than that of the desktop.

The reasons for the large error are as follows:

1. It is greatly affected by the surface roughness, and the smoother the more accurate it is;

2. It is greatly affected by the weight of the workpiece, and the heavier the workpiece tested, the more accurate it is.

3. It is greatly affected by the thickness of the workpiece, and the measurement of too thin workpieces is inaccurate.

In summary: The biggest advantage of the Leeb hardness tester is in large heat treatment workpieces, installed machinery or permanent assembly parts, workpieces with very narrow test space such as mold cavities, rapid inspection of multiple measurement locations in a large range of large workpieces, failure analysis of pressure vessels, automobile generators and other equipment, production lines of bearings and other parts, and material differentiation in large metal material warehouses. The Leeb hardness tester is a rough, rapid measure of the hardness of a specific workpiece material.
