Micro Vickers Hardness Tester

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: first measure optical collimation of mark left diagonals, then compares average resulted with reference tables.

Automatic Model: first optical collimation of mark left diagonals, then read hardness value directly showed on instrument display.

According to: ASTM E384,ASTM E92,ISO 6507,ISO 9385,ISO 4546.
