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.
Successfully combining operability with utility and usability.

Easy to use and highly functional

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

Complies with many industry standards

The Surftest SJ-410 complies with the
following standards: JIS (JIS-B0601-2001,
JIS-B0601-1994, JIS B0601-1982), VDA, ISO­1997, and ANSI.

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.

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.

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.)

Enhanced measuring functions

Traverse direction

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.

Measuring example of stepped

Powerful support for leveling

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.

features: Skidded

Recalculating

Previously measured data can be recalculated for use in other
evaluations by changing the current standard, assessed profile and
roughness parameters.

GO/NG judgement function

An “OK/NG” judgment symbol is displayed when limits are set for
the roughness parameter. In case of “NG,” the calculated result
is highlighted. The calculated result can also be printed out.

The “OK” symbol means the measurement
is within the limits set; “NG” means it is not,
in which case an arrow points to either the
upper or lower limit in the printout.

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 0.5mm. 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.

Assessing a single measurement result under
two different evaluation conditions

A single measurement enables simultaneous analysis under two
different evaluation conditions. A single measurement allows calculation
of parameters and analysis of assessed profiles without the need for
recalculation after saving data, contributing to higher work efficiency.

Arbitrary sampling length setting

This function allows a sampling length to be arbitrarily set in 0.01mm
increments (SJ-411: 0.1mm to 25mm, SJ-412: 0.1mm to 50mm).
It also allows the SJ-410 series to make both narrow and wide range
measurements.

Simple contour analysis function

Point group data collected for surface roughness evaluation is used
to perform simplified contour analysis (step, step height, area and
coordinate variation). It assesses minute forms that cannot be assessed
by a contour measurer.

Step

Step volume

Real sampling

This function samples stylus displacement for a specified time
without engaging detector traverse, which enables use as a
simplified vibration meter or displacement gage incorporated in
another system.
