Features and Benefits

The SJ-500 is a high-precision and high-performance surface roughness tester with a dedicated control unit, achieving user-friendly display and simple operation. The portable SJ-500 surface tester provides highly accurate analysis of surface roughness and fine contours.
  • The SJ-500 is the portable version of the desktop SV-2100 surface roughness tester
  • The SJ-500P is equipped with a desktop PC system
  • Supports measurement in the axial direction by swiveling detector through 90° to analyze shrouded features such as crankshafts
  • Vertical adjustment knob helps to safely position the stylus close to the workpiece and measure inside small holes
  • Digital Adjustment Tilting (DAT) function makes leveling of workpieces ±1.5° easier and more efficient
  • Highly visible, 7.5-inch TFT LCD color display and touch-operated panel provides user friendly, easy operability
  • Dedicated control unit’s built-in joystick allows for quick, easy position
  • Simple input function allows inputs according to drawing instruction symbols of ISO/JIS roughness standards for simple settings of surface roughness measuring conditions
  • Manual column stand is optional for SJ-500 (178-085, 178-089)
