Mitutoyo SJ-210 Surftest Portable Surface Roughness Tester
Standard drive unit, (0.75 mN type)
SKU: 178-561-11E
Performs brilliantly in many situations such as in the quality control room, on the factory floor and on the production line.

With the SJ-210 Series...

You can measure while checking roughness from the waveform!


With the SJ-210 Series...

You don't have to carry large, heavy workpieces because you can measure it on site!

Lightweight and compact, you can measure any side without trouble!



With the SJ-210 Series...

Anyone can measure skidded* measurements easily!

*Measurement method where leveling of the measurement surface is simplified since displacement is measured relative to the ''skid'' that follows the workpiece surface.
