Micro Vickers - SAHV
Among the common hardness testing method, Vickers hardness testing is with most high accuracy and good repeatability.
Low-load Vickers hardness tester is used for hardness testing of small and high precision parts, hardened surface layers and the effective hardened layers depth, coating surface. Micro Vickers hardness testing is mainly used in metal science and metallographic studies to very tiny parts. Test is performed by applying low loads on a pyramidal Vickers indenter. Trough checking and measure of rhombus diagonals left after test, by microscope, the HV value is defined by a simple calculation. A properly sample preparation is an essential procedure to ensure proper measurement. Vickers Hardness Testers are available in two main models with manual or automatic readings.
Manual Model: Reading and manually enter the indentation length value on the touch screen for hardness calculation.
Automatic Model: Get the hardness value with one click.
