8MHBS-3000-4 Electronic Digital Brinell Hardness Tester can display the data of each operation process and test results on the LTD touch screen, and the data of the test results can be output through the printer. This machine is suitable for all kinds of production and processing enterprises, colleges and universities, laboratories of scientific research machinery.

The test process of the machine is displayed on the LCD touch screen, the indentation can be directly measured on the instrument through the micrometer eyepiece, and the diameter of the indentation can be displayed on the LCD touch screen display screen, and the electronic force is applied.

Determination of the Brinell hardness of ferrous metals, non-ferrous metals and bearing alloy materials, with a wide range of applications, suitable for precise measurement of parallel planes, and stable and reliable measurement of curved surfaces.

Main Specifications：

The metal Brinell hardness test system uses a certain diameter of cemented carbide balls, presses into the surface of the material to be tested with a specified test force (Figure 1a). After holding for a specified time, the test force is removed, and the indentation on the surface of the sample is measured (Figure 1b). diameter, to calculate the Brinell hardness, and calculate the：
      HBW=0.102 x 2F/πD（D-）
in the formula：F--------Test force N；
      D-------Ball diameter mm；
      d--------Indentation average diameter mm;
      HBW---Brinell hardness measured with a carbide ball indenter.

For example: 216HBW10/3000/10, when the hardness of 216 is measured with a cemented carbide ball with a diameter of 10mm and a test force of 29.42KN (3000kgf) for 10 seconds, its Brinell hardness is represented by the symbol HBW, and so on.
Product advantages
01  The data of each operation process and test results can be displayed on the large LCD screen. During operation, just measure the indentation and press the eyepiece button, the hardness value can be automatically calculated and displayed on the screen.

02 The data of the experimental results can be output through the printer.


03 There are 14 hardness conversion scales that can be converted.
