Hardness Tester

Hardness Test:

Hardness is the property of a material that enables it to resist plastic deformation, usually by permanent indentation. Indentation hardness measures the resistance of a sample to material deformation due to a constant compression load from a sharp object; they are primarily used in engineering and metallurgy fields. The tests work on the basic premise of measuring the critical dimensions of an indentation left by a specifically dimensioned and loaded indenter.

Hardness Test Methods:

1.Rockwell Hardness Test
2.Rockwell Superficial Hardness Test
3.Brinell Hardness Test
4.Vickers Hardness Test
5.Microhardness Test

Brinell Hardness Tester

XHB-3000 Digital Brinell Hardness Tester



Application:

XHB-3000 Digital Brinell hardness tester is a unified product combining the precise mechanical structure and the load cell control system. The instrument adopts the motorized test force application without weights, and uses 0.5‰ accuracy compression sensor to feedback and the CPU control system to automatically compensate the test force lost during the test. The indentation can be directly measured through the digital measuring eyepiece, and it can intuitively show the test force, indentation length, dwell time, test number, date and time on the large screen. As long as press the eyepiece button after measuring the indentation length, it can automatically get the hardness value and shows on the screen. Test results can be saved for checking or be printed out by the built-in printer, and with RS232 interface for connecting to the computer. According to the client’s requirement, it can be equipped with video measuring device and CCD image automatic measuring system.
