A micro hardness tester is a precision instrument for metal material property inspection in machinery, metallurgy, and other industries, which is widely used in various industries. Among them, micro hardness tester has been widely used in the development, research, practical test, and quality management of metal materials.

3. What are the applications of micro hardness tester?

What are the characteristics of the micro hardness tester?

1. Micro hardness tester is equipped with 10x and 40x objective lens.

2. The micro hardness tester can display the test method, test force, test force holding time, measurement times, etc. on the screen. When operating, just enter the diagonal length of the indentation from the membrane keyboard, and the built-in calculator will automatically calculate the hardness value and display it on the LCD screen.

3. Micro hardness tester has a threaded interface for connecting digital camera and CCD camera, which is convenient to access the special measurement software system for Vickers hardness.

4. Micro hardness tester is the first to use a cold light source in the light source, with a service life of 100,000 hours, but also according to user requirements to choose halogen lamp light source.

5. Micro hardness tester can be an optional CCD image automatic measuring device, also can be optional LCD video measuring device.

6. Micro hardness tester can be an optional Knup indenter, for the measurement of the Knup hardness.

What are the advantages of a micro hardness tester?

1. The hardness value of the micro hardness tester is independent of the size of the test force.

2. As long as the material is of uniform hardness, the micro hardness tester can choose the test force arbitrarily and its hardness value remains unchanged.

3. In a wide range of hardness has a uniform scale, so the micro hardness tester is superior to the Rockwell hardness test.

4. The test force of the micro hardness tester test can be as small as 10gF, the indentation is very small, especially suitable for testing thin and small materials.

5. The indentation of the Vickers test is square, with a clear outline and accurate diagonal measurement.

6. Micro hardness tester has high accuracy and good repeatability.

7. Micro hardness tester measurement range is wide, can measure almost all of the metal materials used in the current industry.

What are the applications of micro hardness tester?

Micro hardness tester can determine the hardness of various raw materials, blanks, semi-finished products, especially other macro hardness tests can not be determined by the fine thin parts and parts of the special parts (such as the edge of the blade, etc.), as well as electroplating layer, a nitride layer, oxide layer, carburizing layer and other surface layers of hardness. A micro hardness tester can also test the hardness of some non-metallic brittle materials (such as ceramics, glass, ore, etc.) and finished products, which are not easy to produce shattering. Finally, the micro hardness tester can test the hardness of the specimen's profile at certain intervals along the longitudinal direction of the specimen (i.e. the test called hardness gradient) to determine the thickness of the plating, nitriding, oxidizing, or carburizing layer, etc. Some other properties of the material can be obtained indirectly through the micro hardness tester. Such as the wear coefficient of the material, the bonding force of concrete in construction materials, the strength of porcelain, etc.

The test force of micro hardness tester is more, as long as the roughness of the workpiece surface meets the standard, micro hardness tester can be detected, so micro hardness tester can be used in many industries. EBPu Electromechanical Equipment (Zhejiang) Co., Ltd. has a long history in the micro hardness tester industry, their mission is to provide one-stop testing solutions to customers and make the test easier.
