1 SJ-210 OVERVIEW
This section explains the structures and the features of the SJ-210.
1.1 Outline of the SJ-210
The Surftest SJ-210 is a shop-floor type surface-roughness measuring instrument, which
traces the surfaces of various machine parts, calculates their surface roughness based on
roughness standards, and displays the results.
■ SJ-210 roughness measurement process
A pick-up (hereinafter referred to as the “stylus”) attached to the detector unit of the
SJ-210 traces the minute irregularities of the work piece surface. The vertical stylus
displacement during the trace is processed and digitally displayed on the liquid crystal
display of the SJ-210.

1.The detector’s stylus traces
the work piece surface
(measurement surface).
2.The up-and-down motion of the stylus
tracing the work piece is converted
into electrical signals.
3.The electrical signals are subject to
various calculation processes.
