Additional information

Enhanced access and inspection capability for integrated surface finish measurement

SFM-C3Features

The C-series of modules have the ability to locate the stylus in small diameter bores. The skid and stylus are inline so that both travel along the axis of the bore.

The SFM-C3 is a replacement for SFM-C2, offering more stylus range and increased robustness without any degradation in performance.

Typical applications

Automotive engine valve guide ways.
