Portable surface roughness testers deliver precise Ra, Rz, Rq and Rt measurements directly on the machine or in the inspection bay. Compact handheld instruments with a diamond stylus pick-up verify machined surface finish to ISO 21920, giving machinists and inspectors immediate confirmation that finish requirements are met.

Verifying Surface Finish with Portable Roughness Testers
Surface finish on machined parts directly affects sealing, wear and fatigue performance, making roughness measurement an essential inspection step. Portable surface roughness testers from our range measure Ra, Rz, Rq and Rt parameters to ISO 21920, so operators can verify finish at the machine without sending parts to a metrology lab.
A diamond stylus traverses the surface at a constant speed while a skidless or skid pick-up follows the profile. Results are shown instantly on a backlit LCD, with selectable cutoff lengths and evaluation lengths to match drawing requirements. Data storage and USB output support digital inspection records.
For comprehensive surface and material verification, pair roughness testing with Portable Hardness Testers and Coating Thickness Testers from our precision measuring instruments range.
