Portable hammer type Brinell hardness testerUsing the principle of Brinell hardness test, the test force is applied by hammering, and the test force is controlled by shear pins. The test force is accurate and the consistency of the test results is good. The test force is F=1580kg, the spherical diameter of the indenter is D=7.26mm, and the F/D2 value is equal to 30. According to the similarity principle of Brinell hardness test, the test results are equivalent to the standard test conditions of 3000kg force and 10mm ball. Good repeatability, relatively high, with an error of no more than 5% HB, far higher than traditional hammer impact Brinell hardness testers.

Application Description:
﹡When using a hammer type hardness tester, regular comparative tests should be conducted with a desktop Brinell hardness tester to verify the test results
The accuracy. The non desktop Brinell hardness tester can be replaced by a C-frame static shear pin hardness tester.
