L-7LSurftestPerforms brilliantly in many situations such as in the quality control room, on the factory oor and on the production line. Mitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.Surftest SJ-410SERIES 178 — Compact Surface Roughness TesterSPECIFICATIONSDramatic 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.(Coordinate difference)• 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.Refer to the Surftest SJ-410 series(Catalog No.E15014) for more details.Optional Accessories for SJ-410 Consumables • Printer paper: Standard type (x5 packs): No.270732 • Printer paper: High-durability type (x5 packs): No.12AAA876 • Protective sheet for the touch
