This portable surface roughness tester is equipped with analysis functionality rivaling that of benchtop surface roughness testers.
Access to functions can be restricted by a password A pre-registered password can limit use of measurement conditions and other settings to the tester’s administrator.
Usually, a spherical or cylindrical surface (R-surface) cannot be evaluated, but, by removing the radius with a filter, R-surface data is processed as if taken from a flat surface.
Surface roughness measurement requires a run-up distance before starting the measurement (or retrieving data). When the SJ-410 Series measures, its run-up distance is normally set to .5mm. This distance, however, can be shortened to 0.15mm using the narrow part measurement function (starting from the origin point of the drive unit). The function extends the possibility of measurement of narrow locations such as grooves in piston ring / O-ring mounts.
