Vickers Hardness Testers

This Vickers hardness tester has a faster testing speed than other ordinary Vickers hardness testers. The hardness value can be displayed directly and need to enter the length of the diagonal. The objective lens and indenter can be shifted automatically after the finished focus. Loading, dwell and unloading the test force automatically. And the objective lens returns to the initial focus status, measuring directly.

Vickers Hardness Testers

This Vickers hardness testers has a faster testing speed than other ordinary hardness testers. The hardness value can be displayed directly and need to enter the length of the diagonal. The objective lens and indenter can be shifted automatically after the finished focus. Loading, dwell and unloading the test force automatically. And the objective lens returns to the initial focus status, measuring directly.

These are specialized instruments used to measure the hardness of materials using the Vickers Hardness Testing method. This method is based on the principle of creating an indentation on the material’s surface using a pyramidal diamond indenter under a specific load. The size of the indentation is then measured, and the Vickers hardness value is calculated based on the indenter’s geometry and the applied load.

Key Features :

Diamond Indenter: The indenter used in the Vickers test is a pyramidal diamond with an angle of 136 degrees between opposite faces. It creates a square-shaped indentation, which allows for precise hardness measurements.
Test Load Range: Vickers Hardness Testers are available in various models with different load ranges, allowing users to select the appropriate test load based on the material’s hardness.
Optical Measurement System: The testers are equipped with an optical measurement system, typically a microscope or an optical system with a camera, to measure the diagonals of the indentation accurately.
Test Force Selection: The operator can choose the test force or load to be applied to the material, depending on the hardness range and the material’s characteristics.
Automatic Testing: Some advanced models feature automatic test cycles, where the tester automatically applies the load, measures the indentation, and calculates the hardness value.
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.
