Form Measurement
A small, lightweight, extremely easy-to-use surface
roughness tester with colour LCD.
The Surftest SJ-210 is a user-friendly surface roughness tester
designed as a handheld tool that can be easily carried and
used on site.
Easy to use
Colour-graphic LCD with backlight
The 2.4” colour screen provides excellent readability and an intuitive display for
easy use of the extensive functionality, with the added convenience of a backlight
for excellent visibility in poor light.
Simple key layout
The Surftest SJ-210 is easily operated using the keys on the front of the unit and
those under the sliding cover.
Highly functional
Advanced data storage capabilities
Up to 10 setups and one measured profile can be stored in the internal memory.
Optional memory card
An optional memory card can be used as an extended memory to store large
numbers of measured profiles and setups.
Password protection
Access to each feature can be password-protected, which prevents unintended
operation and enables settings to be protected.
Multilingual support
The display interface supports 16 languages, which can be freely switched.
Stylus alarm
An alarm warns when the cumulative measurement distance exceeds a preset limit,
so that the stylus can be changed in good time before wear begins to adversely
affect measurement.
Extensive analysis and display features
Complies with relevant industry standards
The Surftest SJ-210 complies with the major VDA, ISO-1997, ANSI and Japanese
standards applying to surface texture measurement.
Displays assessed profiles and graphical data
In addition to calculation results, the Surftest SJ-210 can display sectional
calculation results and assessed profiles, load curves, and amplitude
distribution curves.
Colour-graphics display
Intuitive display that’s clear, sharp, and
The battery charges in one quarter the time
of previous Mitutoyo products.
Large, 2.4-inch LCD
The large screen provides excellent
The backlight improves visibility in poor
lighting conditions.
Drive unit
The drive unit can be separated from the
display unit by using the cable supplied, thus
increasing flexibility in use. Separation and
reattachment is simple.
High-speed USB communication
Data can be transferred to and from a
computer via the high-speed USB interface.
Applicable standards
There is a good choice of drive units and
detectors available to suit almost any
In addition to ISO,
ANSI and VDA, the
Surftest SJ-210 also
complies with JIS
Memory card support
Operation keys
•The keys on the front of the unit and
under the sliding cover are clearly labelled
for ease of use.
•The user-friendly screen layout and arrow keys provide intuitive operation.
•Displayed settings can be changed easily by using the left and right arrow keys.
•Infrequently used keys are hidden under the sliding cover to discourage unintended
Multilingual support
The memory-card slot enables large
quantities of data to be conveniently stored.
The display
interface supports
16 languages.
Many features in a compact form
Extensive display features that assist measurement
•The highly visible LCD with backlight
ensures good screen visibility even in
poor ambient lighting.
•The display mode can be freely switched between portrait and landscape.
•Calculation results are displayed in large characters.
•Pass/fail results are displayed in colour for easy assimilation.
•Assessed profiles, load curves, and
amplitude distribution curves can
be displayed in addition to calculation
•Assessed profiles can also be zoomed
up and down.
Stylus alarm function
•An alarm warns when the cumulative
stylus travel exceeds a preset limit. This
feature can be used to avoid problems
caused by worn-out styli. Any value can
be specified as the limiting distance.
Easy setting
•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.
Advanced features
•The multilingual display interface supports 16 languages, which
can be freely switched.
•Access to functions can be password-protected.
•The battery is a quick charge, long life type.
Setting parameters and recalculating results
•The required parameters can be
selected from the screen. The sub menu also lets you specify detailed
settings such as the tolerance.
After completing measurement,
the parameters can be changed and
calculation can be executed again,
using the new parameters*.
*May not be possible, depending on the setup.
Advanced data storage capabilities
•Interface options: RS-232C output, Digimatic output, printer output, and footswitch input.
•Up to 10 setups can be stored in the internal memory, and these
are quickly retrievable as they are each associated with a specific
•The memory card* slot enables practically unlimited
expansion of the data memory capability.

Detector / drive units
Battery-powered portability scores when making surface roughness measurements on
the shop floor.
Measurements in any orientation can be performed, even upside down. Optional accessories*, such as a height gauge adapter,
allow efficient measurement in almost any situation.
*See pages 8 to 10 for details of the optional accessories available.
The detector, drive unit and display combination means versatility.
Highly capable detectors and drive units
The drive unit can be separated
from the display unit and
reattached via the cable supplied
very easily.

Transverse tracing drive unit
Retractable drive unit
Best suited for measurement of narrow,
shrouded workpiece features such as
crankshaft bearings, EDM parts, etc.
The detector is in the retracted position
at rest so it is immune from damage
when inserted into a feature whose
profile cannot be easily seen, such as a
blind hole, etc.
One of two types may be selected:
1.Measuring force:0.75 mN
Stylus profile: Tip radius 2 μm
Tip angle 60°
2.Measuring force:4 mN
Stylus profile: Tip radius 5 μm
Tip angle 90°.
Optional detectors
•A wide range of optional detectors* is available, including
detectors for small holes, extra small holes, gear tooth surfaces,
and deep grooves.
*See page 7 for details on the detectors.
Carrying case
•A convenient carrying
case is supplied as
standard for
protecting the
instrument in the field.
