SFM-B3 Surface finish probe module

Enhanced access and inspection capability for integrated surface finish measurement
The SFP2 consists of a probe and a range of SFM modules that have been designed to suit the demands of specific parts and features encountered in a precision manufacturing environment. The probe and modules can be automatically interchanged with all other REVO® probe options, providing the flexibility to easily select the optimum tool to inspect a wide range of features. Each SFM module is its own mini-measuring device, incorporating Renishaw’s proprietary scale and read head system, to transduce the motion of the stylus tip.
