Product Description
SP25M is a compact and versatile probe system that provides both scanning capability for form measurement or reverse engineering and touch-trigger probing for geometric size and position measurement.
The SP25M system provides highly accurate scanning measurement with stylus lengths from 20 mm to 400 mm as well as full TP20 touch-trigger probe module compatibility to suit a range of applications.
The SP25M system uses the Renishaw autojoint to enable repeatable mounting to the PH10M PLUS, PH10MQ PLUS and PH6M probe heads. Multiwired extension bar mounting of the SP25M system is also possible to extend the reach and enable more access to part features.
The range of SM25 scanning modules are designed to cover specific stylus length ranges whilst maintaining excellent accuracy performance. The system can be readily expanded to further increase the scanning range, allow TP20 touch-trigger measurement or utilise an automatic changer system.

Renishaw SP25M Scanning Probe Body - RBE
The SP25M comprises two sensors in a single housing. Users can switch between a choice of five scanning modules (which can carry M3 styli with lengths from 20 mm to 400 mm) and an adaptor module that is compatible with Renishaw's TP20 range of probe modules. This capability enables scanning and touch-trigger probing in a single probe system.
