Video Micro Vickers Hardness Tester

Video Micro Vickers Hardness Tester is a specialized instrument used to measure the hardness of materials based on the Vickers hardness testing method. It is an advanced version of the traditional Micro Vickers Hardness Tester with the added capability of using a video camera and image analysis software to measure and analyze the hardness impressions accurately and precisely. The Vickers hardness test is a microhardness testing method that involves applying a specific load through a diamond indenter in the form of a square-based pyramid. The size of the indentation left on the material’s surface is measured, and the Vickers hardness value is calculated based on the indentation’s dimensions.

Description

The testing procedure using a Video Micro Vickers Hardness Tester is similar to the traditional Micro Vickers Hardness Tester. The indenter is pressed into the material surface using a specific load, and the indentation is captured by the video camera. The image analysis software then calculates the hardness value based on the indentation dimensions and provides the hardness measurement in the desired unit (usually in Vickers hardness number, HV). These are widely used in various industries, including materials science, metallurgy, research and development, quality control, and failure analysis. Their ability to provide precise and repeatable hardness measurements on small and delicate samples makes them invaluable tools for assessing material properties and characterizing microstructures.

Feature

Main functions and features:
With digital CCD eyepiece and Data computing systems. Just click one button the hardness value will display on screen directly. Protected by the state patent application of the lift & down system, the machine focus more easily and working more stable; Proprietary ball repositioning system ensure the repeat precision and repeatability of the whole test process. The light strength can be adjusted according to the operator to avoid the visual fatigue for long time operation. With Vickers hardness and Knoop hardness testing capabilities. Automatic measuring the indentation diagonal length, the hardness and conversion hardness will show on the screen directly, no need to check hardness table. Digital screen display hardness value, conversion hardness, testing method, testing force, dwell time, test number and testing process; The built-in printer can print testing times, hardness value, average value, Max. Value, Min. Value, Xmax-Xmin directly, easy for operator to save the data.
