The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100 kgf. The full load is normally applied for 10 to 15 seconds.
The two diagonals of the indentation left in the surface of the material after removal of the load are measured using a microscope and their average calculated. The area of the sloping surface of the indentation is calculated. The Vickers hardness is the quotient obtained by dividing the kgf load by the square mm area of indentation.
Video-Eye Hardness Measuring System is a set of video measurement device to update the traditional optical Brinell hardness tester, Vickers hardness tester, Micro Vickers hardness tester, and Knoop hardness tester as vision hardness tester, it is composed of Eyepiece-Measuring-Camera: #823-811 and Display Monitor: #823-821.
When the optical hardness tester is equipped with this device, the indention is displayed on the monitor #823-821 magnificately, the indention will be observed by many inspectors simultaneously, it makes the measurement of indention more intuitively and accurately, and it reduces operator’s eye fatigue and error to improve the work efficiency obviously.
