A brief introduction
The HV-5 low load Vickers hardness tester is a hardness tester that directly applies test force. Can be used to determine the Vickers hardness of black metals (excluding cast iron) and non-ferrous metals. Due to the small testing force of the machine and the high testing accuracy of the indentation measurement device, it is particularly suitable for measuring the Vickers hardness of thin small parts and surface coatings. This hardness tester is also equipped with a programmable calculator, which makes the calculation of hardness values very fast and accurate. This machine is suitable for Vickers hardness testing in heat treatment workshops and laboratories of departments such as machinery, metallurgy, national defense, scientific research, and universities. It can also be used as a standard Vickers hardness tester by metrology departments.
