The Rockwell hardness tester is a fundamental tool in metal material testing and quality control. In the field of material testing, industries rely on Rockwell hardness testers for sale to accurately measure the hardness of metal materials, helping determine their strength, toughness, and durability. Choosing the right Rockwell hardness tester for sale ensures precision, efficiency, and ease of use in both labs and field applications. As one of the leading Rockwell hardness tester manufacturers and suppliers, Shenyang TX Testing Instruments offers portable Rockwell hardness testers, ideal for on-site hardness testing.

The principle of Rockwell hardness tester for sale is by pressing a specific shape of the indenter (usually a 120° diamond indenter or other diameter carbide ball indenter) into the surface of the material under the specified test force.
The test force is usually divided into initial test force (F0) and total test force (F0 + F1), wherein the main test force F1 is removed after the total test force is held by rockwell tester for sale for a certain time, and the pressing depth is measured when the initial test force F0 is retained.
The hardness is characterized by the difference between the pressing depth under the total test force and the pressing depth under the initial test force, that is, the residual pressing depth. The larger the residual pressing depth is, the lower the hardness is. Conversely, the smaller the residual pressing depth value, the higher the hardness value.
Rockwell metal hardness tester includes desktop type and portable Rockwell hardness tester. The desktop Rockwell hardness tester is usually used in laboratory, and the portable Rockwell hardness tester performs on-site testing with handheld operation. For high-quality options, consider reputable Rockwell hardness tester manufacturers and suppliers.
Select the appropriate combination of the indenter and test force of the Rockwell hardness test equipment provided by TX, a leading hardness tester company based on material type. For example, the commonly used Rockwell HRC scale requires a diamond indenter and a total test force of 150 kgf to measure hardness within the range of 20-70 HRC.
Following the basic principles of the Rockwell test, start with the pointer at 0. First, apply the initial test force using the portable Rockwell hardness tester. Adjust the drum engraving and reading angle as necessary. Then, apply the total test force and hold it for about 5 seconds. Finally, unload the total test force back to the initial test force and read the Rockwell hardness value.
Rockwell hardness tester can directly read the hardness value, the test is rapid, accurate, and the indentation is small, which can be regarded as non-destructive testing, and the batch of finished and semi-finished workpieces can be tested piece-by-piece at the production site.
The calibration of Rockwell hardness tester generally requires the Rockwell hardness tester manufacturers and suppliers or professional calibrators to operate. This process involves using a standard Rockwell hardness calibration block to measure and adjust the test force and ensure the accuracy of the hardness value.
There are three types of standards for Rockwell hardness test in the world. One is ISO 6508, one is ASTM E18, and then there is ASTM E110, which is specifically for portable hardness tester.
