Mitutoyo Surftest SJ-500 | 0.75mN measuring Force
This is a measuring instrument that allows you to easily and accurately measure surface roughness.
The Surftest SJ-500 offers you the following benefits:
- The skidless detector allows you to measure the primary profile (P), roughness profile (R),
waviness profile (W) and more. - User friendly control unit for high precision surface roughness measurement.
- The large 19 cm [7.5”] colour TFT LCD with touch-screen functionality gives you high visibility and ease of use.
- The display menu is easy to read and simple to operate.
- It performs roughness analyses conform to various international standards (EN ISO, VDA, ANSI, JIS) and customized settings.
- The built-in joystick on the control unit enables quick and easy positioning. The manual
adjustment knob allows you to finely position a small stylus to measure the inside surface of small holes. - The detector unit allows a 90° displacement of the stylus, which is ideal for crankshaft and
narrow space measurement. - You can use the instrument stand-alone or mounted on a stand.
