SURFTEST SJ-310 SERIES
PRE 1383
A portable roughness tester with colour LCD and
powerful measurement capability
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 colour 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.
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.
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.
Enhanced power for making measurements on site
Despite its reduced charging time 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.
Extensive analysis and display features
Complies with many industry standards
The Surftest SJ-310 complies with the following standards: DIN EN ISO,
VDA, JIS, ANSI as well as customized settings.
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 14,5 cm (5.7-inch) colour 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).

BAC and ADC curves can be pr inted in addition
to calculation results ( including pass/ fail results) and
assess ed profiles. The printer offers an e asy-tounderstand layout and c an also print horizontally to match
the content d isplayed on the LCD. Furt hermore, printing
speed is ap proximately 50% faster than conventi onal
models.
Built-in battery
With dras tically enhanced p ower compared to
conventio nal models, the Sur ftest SJ-310 can make
1500 continu ous measurements o n a full charge
achieved in 4 hours.

Measuring force : 4 mN
•
Stylus form: Tip radius 5 µm
Tip angle 9 0°
A wide rang e of optional detec tors is available,
including d etectors for sma ll holes, extra sm all holes,
gear toot h surfaces, and dee p grooves.
Drive units
Standard drive unit
• Popular standard drive unit
Transverse tracing drive unit
• Best sui ted for measurement
of narrow, shro uded workpiece
features su ch as crankshaft
bearing s, EDM parts, etc.
(Patent registered in Japan)
Retractable drive unit
• The dete ctor is in the retrac ted
positio n at rest so it is immune
from damag e when inserted in to
a feature wh ose shape cannot be
easily se en, such as a blind hol e, etc.
Links to a wide variety of external instruments
You can save parameter recalculations and measurement results in text format on a memory card and import into commercial spreadsheet software
on a PC. You can also connect to a PC using the USB connector and use a dedicated software application to perform everything from measurement
control and condition modification to issuing inspection result reports.

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.
Icon Tex t
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.
Displaying pass/fail results
By specifying a tolerance in advance, you can display pass/fail results in color.

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.
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 / Patent pending in China)
