surface roughness tester portable, Ra-Rz surface roughness measurement ... Roughness Average (Ra) ... Rz: Rz is the arithmetic mean value of the single roughness depths of consecutive sampling lengths. Z is the sum of the height of the highest peaks and the lowest valley depth within a sampling length.
