Surftest SJ-210 / SJ-310 Surface Roughness Testers



The Mitutoyo Surftest® SJ-210 is an advanced portable surface roughness tester and profilometer that combines high accuracy and measurement speed with numerous innovative features creating a new class leader in surface inspection.

The Surftest® SJ-310 is a user-friendly surface roughness tester that has a high-functionality display with an integrated high-speed built-in printer. This model is a transverse type drive unit with a 0.75mN measuring force.

Features

SJ-210 Models
  • The highly visible 2.4-inch color graphic LCD with backlight lets you view the screen easily even in dark environments.
  • Assessed profiles, load curves, and amplitude distribution curves can be displayed in addition to calculation results. Assessed profiles can also be zoomed up and down.
  • Pass/fail results are displayed in color.
  • The display mode can be easily switched between portrait and landscape.
  • Calculation results are displayed in large characters.
  • Up to 10 measurement conditions can be stored in the internal memory. Conditions can be quickly read according to the workpiece.
  • An optional memory card can be used as an extended memory to store large quantities of measured profiles and conditions.
  • An alarm warns you when the cumulative measurement distance exceeds a preset limit. This feature can be used to prevent problems that would be caused by worn out styli. Any value can be specified as the limit.
  • Many interface options:
    • A USB interface is equipped as standard.
    • The Surftest SJ-210 also provides an RS-232C output, Digimatic output, printer output, and foot switch input.
  • 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.
  • The multilingual display interface supports 16 languages, which can be freely switched.
  • Access to features can be password-protected.
  • A quick-charge, long-life battery is provided.
  • 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 measurement conditions.)

SJ-310 Models

  • Large 5.7” color LCD with touch screen improves operability and achieves high visibility.
  • Statistic measurements up to 3 parameters of 300 samples can be performed showing average, standard deviation, max, min, pass rate and histogram.
  • Up to ten measurement conditions along with stored data can be displayed and printed out by the built-in thermal printer. It can also store up to 10 measurement conditions with the built-in memory.
  • The SJ-310 supports a micro-SD card (optional) for storage of up to 10,000 measurement values, 500 measuring conditions, 1000 measuring data, 500 image (BMP) data, 500 statistic data or auto
    save up to the last 10 sets of measurement data.
  • The total measurement and sectional measurement results can be displayed as well as the evaluation curve, BAC/ADC curve.
  • Security is managed via a password lock to restrict function changes and unnecessary settings that could cause operation errors.
  • 16 languages can be selected and are switchable.
  • It corresponds to cissoidal calculation in which one measurement can evaluate two different conditions.

Detector Information
 
Choice of two Detectors:
Measuring Force: 0.75 mN 4 mN
Stylus Tip: Radius 2 µm Radius 5 µm
Tip Angle: 60° 90°
 

 

When the detector stylus makes contact with the workpiece it is indicated by color coding on 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).   There are a wide range of optional detectors available, including detectors for small holes, extra small holes, gear tooth surfaces, and deep grooves.

Drive Unit Information
 

Standard Drive Unit
Popular standard drive unit
  Transverse Tracing Drive Unit
Best suited for measurement of narrow, shrouded workpiece features such as crankshaft, EDM parts, etc.
  Retractable Drive Unit
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.
