Surftest SJ-500/P Series 178 Surface Roughness Tester
High precision and high performance type surface roughness tester with a dedicated control unit, achieving user-friendly display and simple operation
- User-friendly display and simple operation equipped with a highly visible color 7.5-inch TFT LCD.
- Easy positioning A joy stick built in the dedicated control unit allows easy and quick positioning. Fine positioning of a small stylus, required for measuring the inner side of a small hole, can be easily made using the 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.
