Surface Roughness Testers
Compare TESA portable roughness instruments and roughness/profile configurations. Choose the required surface parameters, stylus access and measurement settings before selecting a model.
What can you measure?
Finish on functional surfaces
Inspect accessible sealing faces, bearing seats and machined surfaces with the appropriate stylus direction and traverse arrangement.
Profile geometry on suitable configurations
Review the RUGO-SURFACE profile function and required profile set separately from a routine roughness trace.

This comparison describes product families and configurations. Confirm the exact range, permissible error, accessories and documentation with the selected part number. Display resolution alone does not state measurement accuracy.
What to consider before choosing
Surface requirement
Provide the parameter definition, permitted value, filter and evaluation length from the inspection specification.
Stylus access
Describe the surface size, curvature, bore/recess depth and available traverse path.
Verification and records
Include the suitable reference standard, support arrangement and required software or output connection.
Frequently asked questions
Does measuring Ra also check contour geometry?
Ra is a roughness parameter. Contour or profile geometry requires the appropriate acquisition and evaluation function; review the RUGO-SURFACE profile configuration when required.
Can any standard probe reach an internal surface?
Check the exact stylus geometry, reach, clearance and traverse length against the bore or recess. Specify the internal feature drawing.
Is Bluetooth included with every instrument?
The listing distinguishes variants with and without Bluetooth for relevant families. Confirm the exact variant and receiving workflow.
How do I obtain comparable surface results?
Use the specified parameter definition, filter, measurement direction, evaluation length and suitable verification standard. Keep the method consistent between measurements.
