Fine Marketing is meeting demand for testing machines, since 1996. The hardness tester is a testing device that is utilized for testing material hardness. There are many models of this device, for instance Rockwell, Vickers, Brinell, Shore A, to name a few. Every model of hardness tester works differently. Brinell hardness tester is used to determine Brinell hardness, by forcing a hardened steel/carbide ball into surface to measure diameter indentation using a microscope. Rockwell hardness tester also has its own unique measuring technique and is widely used in metalworking plant. When it comes to Vickers hardness tester, this testing device is used to measure hardness of thin sheets and very hard material.
