MITECH MHBS-62.5 Digital Display Small Load Brinell Hardness Tester
Mitech MHB-62.5 Digital Display Small Load Brinell Hardness Tester, based on the mechanical principle of hard alloy indenter pressing into the sample surface to produce indentation, realizing the material hardness measurement by measuring the diameter of the indentation. It’s MITECH latest optical mechanical and electrical integration of high-tech products. It is novel and high reliable with accurately measurement. With LED display, simple operation, it can visually display the test results to meet the hardness testing requirement for the quality control and qualified assessment of the workpiece sample. It is widely used in metal processing and manufacturing, various metal material’s failure analysis and other fields like colleges and research institutions.It is the new type Brinell hardness testing instrument for testing the hardness of the materials like cast iron, steel, soft alloy with small and thin sheet type workpiece and so on.

Hardness is not a simple physical quantity, but a reflection of the material elasticity, plasticity, strength and toughness .and hardness test is the most simple mechanical testing method to determine the metal material performance. Also one of the important means to judge the products quality.
Brinell hardness test: Test force(F) is on the steel ball with certain diameter(D) , pressed on sample surface. After a period of time, cancel the force. The indentation diameter is get by measuring with micrometer ocular,thus to calculate the average pressure(N/mm²).Then we can get the Brinell hardness of the sample as below:
Tips:F—Test force on steel ball,unit:N
D—Diameter of steel ball ,unit:mm
d—Indentation diameter,unit:mm
0.102—Rule coefficient
