Form Talysurf® PGI NOVUS

Advanced Surface Finish, Contour, 3D & Diameter Measuring Equipment

The Form Talysurf® PGI NOVUS is the most advanced system for surface finish, contour, 3D and diameter measurement, delivering unique benefits for both design and production. This instrument is designed with class leading 20 mm gauge range with 0.2nm resolution with the capability to measure surface finish (roughness, form, waviness) diameter, included angle, in a normal and inverted direction with the same speed and accuracy.

This system is an ideal solution for bearings, injectors and precision component manufacturers. Get instant measurement analysis feedback like surface finish, contour and topography with Metrology 4.0 software.

  • Overview +

    At the heart of the Form Talysurf® PGI NOVUS is a ground-breaking dual bias gauge. It is an advanced surface finish, 3D, diameter and contour measuring equipment.

    The Form Talysurf® PGI NOVUS surface finish measuring instrument delivers 20 mm gauge range with a standard 100 mm stylus. The PGI NOVUS gauge has been designed to provide the user with greater measurement flexibility.

    Small, medium and large complex parts can be measured on a single system. Buy with confidence and future-proof your investment. Using a 200 mm stylus provides an industry-leading 40 mm gauge range with full surface finish capability.

    Key features

    • Automated force control
    • Automatic lift-lower
