Easy and safe measurements that anyone can perform efficiently
The high-visibility color-graphic LCD touch screen displays calculated results and assessed profiles. A backlight enables comfortable viewing even under poor lighting conditions.
A single measurement enables simultaneous analysis under two different evaluation conditions. A single measurement allows the calculation of parameters and analysis of filtered profiles without the need for recalculation after saving data, which contributes to higher work efficiency.
Higher level of quality control
Anyone can easily perform high-level data collection.
Wireless and quick capture of measurement results on a PC. No more handwriting, and also easy data input with a single touch.
Higher accuracy measurements with selectable drive unit.
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 0.5 mm. However, this distance can be shortened to 0.15 mm using the narrow-part measurement function. This function extends the measurement of narrow locations to features such as piston-ring grooves and O-ring grooves.


Easily measures R-surface roughness (skidless measurement)
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. Other curved surfaces can be processed such as parabolical and ellipsoidal.
Supporting not only surface roughness measurement but also contour (fine contour) measurement
Point group data collected for surface roughness evaluation is used to perform simplified contour analysis (step, step height, area and coordinate difference). It assesses minute forms that cannot be assessed by a regular contour measuring machine.


Your choice of skidless or skidded measurement
Skidless measurement
Skidless measurement is where surface features are measured relative to the drive unit reference surface. This measures waviness and finely stepped features accurately, in addition to surface roughness, where range is limited to the stylus travel available.
Skidded measurement
In skidded measurements, surface features are measured with reference to a skid following close behind the stylus. This cannot measure waviness and stepped features exactly, but the range of movement within the measurement made is greater because the skid tracks the workpiece surface contour.
