Roughness tester

Roughness or roughness is a measure to determine the texture of the surface and is determined by determining the amount of vertical changes on the surface compared to the real smooth surface. If these changes are large, the surface is rough and if low is soft. This quantity plays an important role in determining the interaction Objects are held together and knowing this will make many behaviors of mechanical components predictable. For example, rough objects are more prone to corrosion and cracking. They use different contact and non-contact methods to measure roughness.
Conventional equipment for measuring roughness, known as the roughness tester, uses the contact method, and a head such as a gramophone needle moves on the surface to determine the surface roughness due to the frequency of oscillations and maximum displacement.
