Classification of Sclerometers [Full]

Generally speaking, the higher the hardness, the better the wear resistance. Commonly used hardness indicators include Leeb hardness, Brinell hardness, Rockwell hardness and Vickers hardness. What are the categories of Hardness Testers?

There are many classifications of Hardness Testers, and the following will introduce the classification of Hardness Testers.

  1. Rockwell Hardness Tester

Used for testing the hardness of various steels (including alloy steel and stainless steel). This is an important and commonly used type of Hardness Tester. There are the following:

  ① Rockwell Hardness Tester

  ② Electric Rockwell Hardness Tester

  ③ Digital Rockwell Hardness Tester

  ④ Digital display surface Rockwell Hardness Tester

  ⑤ Digital Rockwell, surface Rockwell Hardness Tester

  2. Vickers Hardness Tester

Used to measure the hardness of ferrous metals, non-ferrous metals, cemented carbide (such as aluminum alloy) and surface carburizing and nitriding layers, expressed by HV.

  3. Brinell Hardness Tester

Brinell Hardness Tester measures unquenched steel, cast iron, non-ferrous metals and soft bearing alloy materials, expressed in HBW.

  4. Blovey Hardness Tester

That is, it can be used as a Hardness Tester with three kinds of hardness: Brinell, Rockwell, and Vickers. It is more suitable for development and research.

 5. Shore Hardness Tester

(Also known as Shore Hardness Tester, this is because the Hardness Tester is called by the surname of foreigners, and there are different Chinese characters for different transliterations). There are only two kinds of HA and HD, the former is the hardness parameter of softer rubber, and the latter is the hardness parameter of harder rubber or plastic.

  6. FISCHERSCOPEH100C of German FISCHER company

It is a computer-controlled measuring instrument for microhardness testing. Mainly used for hardness measurement of electroplating layers, paint layers, organic layers, etc., with a minimum of 1 micron coating.

  7. Leeb Hardness Tester

This is a smaller Hardness Tester that can convert various hardness values. Mainly used for testing metal materials, especially for larger workpieces.

 8. Pencil Hardness Tester

This is used to detect the hardness of the coating. To clip a pencil on the "trolley" and let it slide on the coating, the hardness of the coating is judged according to the hardness of the pencil and the scratches on the coating.
