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  hen 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 detectors and drive units

Detector supplied as standard

A wide range of optional detectors is available, including detectors for small holes, extra small holes, gear toot surfaces, and deep grooves.

•Standard drive unit
• Popular standard drive unit

 

 

 

•Transverse tracing drive unit
• Best suited for measurement of narrow, shrouded workpiece features such as crankshaft bearings, EDM parts, etc. (Patent Registered in Japan)

Retractable drive unit
• The detector is in the retracted position at rest so it is immune from damage when inserted into a feature whose shape cannot be easily seen, such as a blind hole, etc.

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.

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
