Surftest- SJ-500/P Series 178

High precision and high performance compact surface roughness tester with a dedicated control unit, achieving user-friendly display and simple operation.

FEATURES:

User-friendly display and simple operation Equipped with a highly visible color 7.5 inch TFT LCD, employing a color icon display and a touch panel achieves user-friendly display and simple operation.

• Easy positioning. A joystick built into the dedicated control unit allows quick and easy positioning. Fine positioning of a small stylus, required for measuring the inner side of a small manual knob                                                                                                  
• Easy setting of measuring conditions for surface roughness. Equipped with simple input function allows inputs according to drawing instruction symbols of ISO/JIS roughness standards. Troublesome measuring condition settings can be easily input by directly selecting a drawing instruction symbol for surface roughness from the menu.
• Wide variety of analyses Numerous form analyses (convex step, re-entrant step, superficial content, radius, angle coordinates, step and indication angle) are available, in addition to 43 type analysis parameters compliant with 1997 ISO and 2001 JIS surface roughness standards
