Rich choice of options provide easier, smoother and more accurate measurements. The portable surface roughness tester evolves as the Mitutoyo SJ-410 large touch-screen, color-graphic LCD ensures both intuitive control and advanced operability


  • Both skidded and skidless measurement are possible with this series. Equipped with 46 roughness parameters that conform to the latest ISO, DIN, ANSI, and JIS standards.
  • A wide-range, high-resolution detector and a drive unit provide superior high-accuracy measurement in its class.
  • A skidless detector and a curved surface compensation function provide efficient evaluation of cylinder surface roughness.
  • Ultra-fine steps, straightness and waviness can be measured by using the skidless measurement function.
  • The handheld data processing unit and the 5.7-inch color graphic LCD touch-panel provides superior readability and operability. The LCD also includes a backlight for improved visibility in dark environments.
