The Surftest SJ-310 is a compact, portable, easy-to-use surface
roughness measurement instrument equipped with extensive
measurement and analysis features.
Easy to use
Large color graphic LCD
The color touch-screen provides excellent
readability and an intuitive display that is easy
to negotiate. The LCD also includes a backlight
for improved visibility in dark environments.
The integrated printer allows you to print
measurement results on the spot.
Enhanced power for making measurements on site
Despite its reduced charging time — approximately 1/4 that required for conventional
models, the Surftest SJ-310 is capable of making approximately 2.5 times the number
of measurements when fully charged. The detector supports a variety of measurement
orientations and can make measurements up against a wall surface or while facing upward.
When combined with optional accessories such as a height gauge adapter, the detector can
make measurements in various orientations and settings.
Highly functional
Internal memory
Up to 10 measurement conditions and one measured
profile can be stored in the internal memory.
Optional memory card
The optional memory card can be used as an
extended memory to store large quantities of
measured profiles and conditions and adds the
convenience of automatically saving data from
the 10 most recent measurements (Trace 10).
Password protection
Access to each feature can be password-protected,
which prevents unintended operations and allows
protection of your settings.
Multilingual support
The display interface supports 16 languages, which
can be freely switched.
Stylus alarm
(patent pending in Japan, U.S.A., EU)
An alarm warns you when the cumulative
measurement distance exceeds a preset limit.
Extensive analysis and display features
Complies with many industry standards
The Surftest SJ-310 complies with the following
standards: JIS (JIS-B0601-2001, JIS-B0601-1994, JIS
B0601-1982), VDA, ISO-1997, and ANSI.
Displays assessed profiles and graphical data
In addition to calculation results, the Surftest SJ-310
can display sectional calculation results and assessed
profiles, load curves, and amplitude distribution curves.

User friendly, high-functionality display unit with integrated high-speed printer
The large 5.7-inch color graphic touch-screen LCD provides excellent readability. Furthermore, selecting icons from the touch panel display*
1
provides intuitive and easy operation. The integrated high-speed printer also allows the user to perform the entire process from making
measurements to printing the results with the push of a single button (START button).
*1 Text display can also be selected.
Printer5.7-inch color graphic LCD
with touch screen
BAC and ADC curves can be printed in addition
to calculation results (including pass/fail results)
and assessed profiles. The printer offers an
easy-to-understand layout and can also print
horizontally to match the content displayed on the
LCD. Furthermore, printing speed is approximately
50% faster than conventional models.
Built-in battery
With drastically enhanced power compared
to conventional models, the Surftest SJ-310
can make 1,500 continuous measurements
on a full charge achieved in 4 hours.

Measurement assistance and analysis features
offering the ultimate in ease of use
Switches between icon and text display
The display can be switched between icon and text, providing easy, user-friendly operation.
Additionally, the guidance feature provides detailed explanations of touch-screen buttons.
IconText
Easy specification of assessment conditions from a list
Setting assessment conditions is simple because you can select the desired condition from a displayed list (e.g., standard, parameter).
Zooming waveforms and analyzing coordinate differences
You can not only
magnify or shrink
waveforms, but also
calculate the coordinate
difference between
two points using a ruler
operation.
You can quickly check
the irregularity status
without waiting for a
printout.
Deleting unnecessary data
With the Surftest
SJ-310, you can
delete portions of
measurement data.
This feature allows
you to make new
calculations by deleting
data that should not be
included in parameter
calculation, such as
data on a scratch.
Displaying pass/fail results
By specifying a tolerance in advance, you can display pass/fail results in color.
Surface texture symbol entry
You can enter assessment conditions using
ISO/JIS surface texture symbols.

Measurement results can be displayed in several ways
Measurement results can be presented in the form of a 1-parameter, profile, 4-parameter or trace display.
1-parameter display: one parameter
measurement result
Profile display: one parameter measurement
result and the measured profile
4-parameter display: four parameter
measurement results
Trace display: the ten latest measurement
results using the same parameter
Recalculation function
After completing measurement, you can modify the assessment conditions (standard, profile, and parameter) and easily recalculate the results using
the new condition.* *
Not possible with all measurement conditions.
Dual assessment of a single measurement
Using the result of a single measurement, you can make calculations or
analyze assessment profiles under two different assessment conditions
(standard, profile, filter, etc.) without using the recalculation feature.
Stylus alarm function
Displayed settings can be easily changed by pressing the left and right
arrow keys under the sliding cover. For example, these keys can be used
to switch the cut-off value(λc) and the number of sampling lengths (N)
on the measurement screen. (Patent pending in Japan.)
Positive stylus contact indication
Stylus contact with the workpiece is indicated by color coding
in the display. This is helpful when visibility of the surface to be
measured is restricted (e.g. when measuring within a shrouded
feature or groove).
Extensive statistical processing features
You can make a maximum of 300 statistical measurements using up to three
parameters to obtain averages, standard deviations, maximums, minimums,
passing rates, and histograms (upper and lower limits can be displayed).
This feature is ideal for day-to-day data management.

The Surftest SJ-310 is a compact, portable, easy-to-use surface
roughness measurement instrument equipped with extensive
measurement and analysis features.
Easy to use
Large color graphic LCD
The color touch-screen provides excellent
readability and an intuitive display that is easy
to negotiate. The LCD also includes a backlight
for improved visibility in dark environments.
The integrated printer allows you to print
measurement results on the spot.
Enhanced power for making measurements on site
Despite its reduced charging time — approximately 1/4 that required for conventional
models, the Surftest SJ-310 is capable of making approximately 2.5 times the number
of measurements when fully charged. The detector supports a variety of measurement
orientations and can make measurements up against a wall surface or while facing upward.
When combined with optional accessories such as a height gauge adapter, the detector can
make measurements in various orientations and settings.
Highly functional
Internal memory
Up to 10 measurement conditions and one measured
profile can be stored in the internal memory.
Optional memory card
The optional memory card can be used as an
extended memory to store large quantities of
measured profiles and conditions and adds the
convenience of automatically saving data from
the 10 most recent measurements (Trace 10).
Password protection
Access to each feature can be password-protected,
which prevents unintended operations and allows
protection of your settings.
Multilingual support
The display interface supports 16 languages, which
can be freely switched.
Stylus alarm
(patent pending in Japan, U.S.A., EU)
An alarm warns you when the cumulative
measurement distance exceeds a preset limit.
Extensive analysis and display features
Complies with many industry standards
The Surftest SJ-310 complies with the following
standards: JIS (JIS-B0601-2001, JIS-B0601-1994, JIS
B0601-1982), VDA, ISO-1997, and ANSI.
Displays assessed profiles and graphical data
In addition to calculation results, the Surftest SJ-310
can display sectional calculation results and assessed
profiles, load curves, and amplitude distribution curves.

User friendly, high-functionality display unit with integrated high-speed printer
The large 5.7-inch color graphic touch-screen LCD provides excellent readability. Furthermore, selecting icons from the touch panel display*
1
provides intuitive and easy operation. The integrated high-speed printer also allows the user to perform the entire process from making
measurements to printing the results with the push of a single button (START button).
*1 Text display can also be selected.
Printer5.7-inch color graphic LCD
with touch screen
BAC and ADC curves can be printed in addition
to calculation results (including pass/fail results)
and assessed profiles. The printer offers an
easy-to-understand layout and can also print
horizontally to match the content displayed on the
LCD. Furthermore, printing speed is approximately
50% faster than conventional models.
Built-in battery
With drastically enhanced power compared
to conventional models, the Surftest SJ-310
can make 1,500 continuous measurements
on a full charge achieved in 4 hours.

Measurement assistance and analysis features
offering the ultimate in ease of use
Switches between icon and text display
The display can be switched between icon and text, providing easy, user-friendly operation.
Additionally, the guidance feature provides detailed explanations of touch-screen buttons.
IconText
Easy specification of assessment conditions from a list
Setting assessment conditions is simple because you can select the desired condition from a displayed list (e.g., standard, parameter).
Zooming waveforms and analyzing coordinate differences
You can not only
magnify or shrink
waveforms, but also
calculate the coordinate
difference between
two points using a ruler
operation.
You can quickly check
the irregularity status
without waiting for a
printout.
Deleting unnecessary data
With the Surftest
SJ-310, you can
delete portions of
measurement data.
This feature allows
you to make new
calculations by deleting
data that should not be
included in parameter
calculation, such as
data on a scratch.
Displaying pass/fail results
By specifying a tolerance in advance, you can display pass/fail results in color.
Surface texture symbol entry
You can enter assessment conditions using
ISO/JIS surface texture symbols.
(Patent registered in Japan, U.S.A., Germany, UK, France)

Measurement results can be displayed in several ways
Measurement results can be presented in the form of a 1-parameter, profile, 4-parameter or trace display.
1-parameter display: one parameter
measurement result
Profile display: one parameter measurement
result and the measured profile
4-parameter display: four parameter
measurement results
Trace display: the ten latest measurement
results using the same parameter
Recalculation function
After completing measurement, you can modify the assessment conditions (standard, profile, and parameter) and easily recalculate the results using
the new condition.* *
Not possible with all measurement conditions.
Dual assessment of a single measurement
Using the result of a single measurement, you can make calculations or
analyze assessment profiles under two different assessment conditions
(standard, profile, filter, etc.) without using the recalculation feature.
Stylus alarm function
Displayed settings can be easily changed by pressing the left and right
arrow keys under the sliding cover. For example, these keys can be used
to switch the cut-off value(λc) and the number of sampling lengths (N)
on the measurement screen. (Patent pending in Japan.)
Positive stylus contact indication
Stylus contact with the workpiece is indicated by color coding
in the display. This is helpful when visibility of the surface to be
measured is restricted (e.g. when measuring within a shrouded
feature or groove).
Extensive statistical processing features
You can make a maximum of 300 statistical measurements using up to three
parameters to obtain averages, standard deviations, maximums, minimums,
passing rates, and histograms (upper and lower limits can be displayed).
This feature is ideal for day-to-day data management.
