The SJ-500 is the portable version of the desktop SV-2100 surface roughness tester, offering the same functionality in a portable form factor.
The SJ-500P model comes equipped with a desktop PC system, providing extended capabilities for data analysis and storage.
It supports measurements in the axial direction by swiveling the detector through 90°, making it possible to analyze shrouded features such as crankshafts.
The vertical adjustment knob allows for precise positioning of the stylus close to the workpiece, enabling measurements inside small holes and confined spaces.
