Instrument features
1. Wide range of applications, high precision;flat /
curved portable portable surface roughness meter.
◇Measuring range / clarity value : 800 um ~ 8 um /
0.000125 um ( 在 8 um Measuring range ).
2. 35 kinds of surface roughness measurement results
parameters, in line with international norms --
ISO、DIN、ANSI、JIS (1994/1982 ).
3. Cylindrical, circular surface measurement and
compensation function, easy to complete the
desired results.
4. For the polished surface, plane, step can be measured
and surface characteristics for the LCD screen to do
the analysis.
5. Expand the wide, in the future optional computer software
(SURFPAK-SJ) for analysis and report print storage.
6. Touch-screen operation panel and large LCD screen;
easy display of the determination process and the
results printed.
