Electronic Brinell Hardness Tester MHB-3000

Mitech MHB-3000 Electronic 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 is novel and high reliable with accurately measurement. LED eight digital tubes and luminescent secondary tube 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 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 simplest 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).

Working Temperature：18℃～28℃；

Relative Humidity：≤65％；

Clean environment, no vibration；

No corrosive media around.

Suitable for measuring the surface is more rough cast iron, steel and other non-homogeneous specimen Brinell hardness;

Using electronic automatic loading system, remove the load weight;

With ten test force, a wider range of tests, higher precision;l

The control part is the closed-loop control system, which can dynamically reflect real load changes.

Modeling novel, strong structure,high reliability and operability , intuitive, high test efficiency;

Equipped with excellent performance of the carbide indenter, high hardness, wear resistance, good toughness, while hightemperature,

corrosion resistance, to ensure that the instrument measured standard, stable and reliable;

Host stability is good, the workpiece surface quality and man-made factors on the hardness of the test results less impact;

Panel with two-color LED display, red for small gear, green for large-scale force;

Compliance with ISO 6506, ASTM E10-12, ASTM E-384, GB / T231.2, JIS Z2243 and other relevant domestic and foreignstandards.
