Surftest SJ-410 SERIES 178 — Compact Surface Roughness Tester

Dramatic improvement on compact type surface roughness testers
• Equipped with the touch-screen large color graphic LCD to achieve both of the intuitive operation and high operability
• Skidded and skidless measurement are switchable to perform the optimum evaluation according to the measurement condition.
• A wide-range, high-resolution detector and a drive unit provide superior high-accuracy measurement in its class.
・Detector
　 Measuring range: 800μm
　 Resolution: 0.0001μm (at 8μm range)
・Drive unit
　 Straightness / traverse length: 0.3μm/25mm (SJ-411)
　 Straightness / traverse length: 0.5μm/50mm (SJ-412)
• 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
