We are engaged in providing the broad assortment of 'Surface Riughness Tester'.
7061 MarSurf PS1 Surface Roughness Tester' that is light weight and portable measuring solution for the range of surface roughness measurements required for compliance to International Standards. Not only it measures the peak-to-valley height but also gives you the frequency of peaks encountered on a sample area. A wide range of stylus pick-ups and accessories are also available from Elcometer to suit all your inspection needs.
Rt: The distance between the highest peak and the lowest valley within any given sampling length.
Rz: The average distance between the highest peak and the lowest valley over a number of sampling lengths.

Not only it measures the peak-to-valley height but also gives you the frequency of peaks encountered on a sample area. A wide range of stylus pick-ups and accessories are also available from Elcometer to suit all your inspection needs.
Surface roughness testers consist of a stylus which is mechanically drawn across the surface recording an 'image' of the surface roughness across a pre-defined sample length. The measurement technique provides a number of measurement parameters including:
Rmax: The greatest distance between the highest peak and lowest valley over the sampling length.
Ra: The average surface roughness over the sampling length.
Rt: The distance between the highest peak and the lowest valley within any given sampling length.
Rz: The average distance between the highest peak and the lowest valley over a number of sampling lengths.
