The lightweight, compact and very easy to use Mitutoyo Surftest SJ-210 Series 178 Portable Surface Roughness Testers have arrived at!  The SJ-210 series all you to view surface roughness waveforms right on the LCD screen.

  • 2.4-inch color graphic LCD with backlight
  • Optional memory card
  • Password protection
  • Multilingual support
  • Stylus alarm
  • Complies with many industry standards
  • Displays assessed profiles and graphical data
  • Free Software available!

The drive unit can be separated from the display unit by using a cable, allowing more flexible measurement. The driver can be separated and reattached in one simple step

Drive Unit Options:

 1) Standard drive unit
Popular standard drive unit

2) Transverse tracing drive unit
Best suited for measurement of narrow, shrouded workpiece features such as crankshaft, EDM parts, etc. (Patent Registered in Japan)

3) Retractable drive unit
The detector is in the retracted position at rest so it is immune from damage when inserted into a feature whose profile cannot be easily seen, such as a blind hole, etc.
