Enhanced power for making measurements on site

Color-graphic LCD
The color-graphic LCD with excellent visibility displays calculated results and assessed profiles even clearer. This is useful fo  checking results without printing them out.

Backlight provided
A backlight improves usability in dim testing environments.

 

Touch screen for easier operations

The screen display can be switched between icon display and text display.

Easy to use and highly functional

This portable surface roughness tester is equipped with analysis functionality rivaling that of benchtop surface roughness testers.

Multilingual support

Password protection

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.

More measuring functions than expected from a compact tester

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.

Narrow space measuring function

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.
