MarSurf XR1 – Surface Roughness Measurement

The ideal instrument for a low-cost introduction to user-friendly surface metrology. The PC-based instrument delivers all common surface parameters and profiles in accordance with international standards, both in the measuring room and in production. MarSurf XR 1 from Mahr stands for innovative roughness evaluation software.
Key Features:
– Over 80 surface parameters for R-, P- and W-profiles according to current ISO/JIS or MOTIF standards (ISO 12085)
– Bandpass filter Ls in accordance with current standard; Ls can also be switched off or varied as required
– Comprehensive measuring records
– Teach-in methods for the rapid creation of Quick&Easy measuring programs
– Automatic functions for choosing cut-off and traversing length in accordance with standards
– Support for various calibration methods (static and dynamic) by specifying the Ra or Rz parameter
