Micro Vickers Hardness Tester
These Micro Vickers hardness tester have a faster testing speed than other ordinary Vickers hardness testers. The hardness value can be displayed directly and needs to enter the length of the diagonal. The objective lens and indenter can be shifted automatically after the finished focus. Loading, dwelling, and unloading the test force automatically. And the objective lens returns to the initial focus status, measuring directly. The optical system designed by our senior optical engineer not only meets the definition of hardness testing requirements but also can observe the microstructure of the material, the image is very clear. Casting aluminum moulding shell to ensure structure more stable; Adopted car painting technology, pure white color looking more decent; High scratch resistance capability, used for years still brightness like new.
It is a specialized instrument used to measure the microhardness of materials, particularly small or thin samples. It is an extension of the Vickers Hardness Testing method, which is based on the principle of measuring the indentation produced by a pyramidal diamond indenter under a specific load. The Vickers Hardness Test is commonly used to determine the hardness of materials with fine microstructures, thin coatings, or small parts that cannot be tested using traditional macrohardness testing methods, such as Rockwell or Brinell. The Micro Vickers Hardness Tester is specifically designed to perform Vickers hardness testing at lower loads and smaller indentation sizes, enabling precise measurement of microhardness.
Key Features
- Diamond Indenter: The indenter used in the Micro Vickers test is typically a pyramidal diamond with an angle of 136 degrees between opposite faces. This shape allows for a small, square-shaped indentation, which is ideal for microhardness testing.
- Load Range: Micro Vickers Hardness Testers are capable of applying very light loads, often ranging from a few grams to a few kilograms. This low load range is suitable for testing delicate or small samples.
- Optical Measurement System: The tester is equipped with an optical measurement system, typically a microscope or an optical system with a camera, to measure the indentation diagonals accurately.
- Test Force Selection: The operator can select the appropriate test force based on the material and the expected hardness range.
- Automatic Indentation Measurement: Some models feature automated indentation measurement and image analysis, reducing human error and improving testing efficiency.
- Data Display and Analysis: The measured hardness values are displayed digitally, and the tester may have data storage and analysis capabilities for record-keeping and quality control purposes.
