Portable surface roughness tester evolution
Rich choice of options provide easier, smoother and more accurate
measurements
Portable surface roughness tester evolves!
The large touch-screen, color-graphic LCD ensures both intuitive control and advanced operability
Applicable standardsEnhanced 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 really useful for
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.

A variety of interfaces supplied as standard
The external device interfaces that come as standard include USB, RS232C, SPC output and footswitch I/F.
Memory card (optional) is supported
The measurement conditions and data can be stored in a memory card
(optional) and recalled as required. This enables batch analysis and
printout of data after on-site measurement.

Key-sheet buttons
A sturdy key-sheet-button panel with superior durability in any environment is provided. For repeat measurement of the same work,
simply pressing the start switch can complete measurement,
analysis and printout.
Printer
High-speed printer prints out measurement results on site
A high-quality, high-speed thermal printer prints out measurement results.
It can also print a BAC curve or an ADC curve as well as calculated
results and assessed profiles. These results and profiles are printed out
in landscape format, just as they appear on the color-graphic LCD.
Carrying case
The unit is easily transported in a dedicated carrying case
which includes holders for the accessories as well as the
tester itself. (Standard accessory.)

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 roughnness, but
range is limited to the stylus travel available. The SJ-410 series supports
a variety of surface feature measurements simply by replacing the
stylus.

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 which measurement can be made is greater because the skid
tracks the workpiece surface contour.

The height/tilt adjustment unit comes as standard for leveling the drive unit prior to making skidless measurements and, supported by guidance from
the unique D.A.T. function, makes it easy to achieve highly accurate alignment.
