Roughness gauge TESA

With TESA Roughness gauges customers can use a number of features for measuring roughness or profile of a surface

Мain parameters:

• Ra - the arithmetical mean of the absolute values related to the profile deviation y within the reference length
• Rmax - vertical distance between the highest peak and the deepest valley within a sampling length
• Rz - the arithmetical mean of the absolute values related to the 5 highest peak and 5 deepest valleys within a sampling length
