Surftest SJ-410 Compact Surface Roughness Tester | Mitutoyo by Muser
Mitutoyo SJ-410 | Compact Surface Roughness Tester
Features
- Equipped with a large, touch-screen color graphic LCD to achieve both intuitive operation and high operability.
- Skidded and skidless measurement are switchable to perform optimum evaluation according to the measurement setup.
- A wide-range, high-resolution detector and a very accurate drive unit provide superior high- accuracy measurement in its class.
- Simplified contour analysis (Step, Step quantity, Area, Coordinate difference) is available using the point cloud data collected to evaluate the surface roughness.
- Allows the evaluation of detailed shapes that cannot be achieved by contour measuring instruments.
- Allows the evaluation of surface roughness in a circumferential direction using the skidless measurement and R-surface compensation functions.
- Conforms to the latest ISO standard and ANSI / VDA standard in addition to the JIS standard (2001 / 1994 / 1982).
- Achieves the performance of a desktop type surface roughness tester in combination with the simplified stand and associated optional accessories.
