Skidless tracing made perfect

For 50 years Mahr has been defining the highest standards in surface texture metrology. Our products serve as a guidance to others. Especially Mahr"s drive-unit family is a class by itself – a fact that is again proved with the new PGK 120 drive unit.

• Up to 120 mm (4.72 in) tracing length for all roughness and waviness measurements you can imagine
• Extremely low straightness deviation of the X-axis: < 0.3 µm/120 mm (< 12 µin/4.724 in)
• Hardly detectable - the residual noise:
  The residual Rz value amounts to < 30 nm (1.18 µin)
• Patented motor-driven pick-up zero setting within a range of 22 mm (.866 in) saving set-up work and time
• Automatic measuring runs: pick-up lowering - zero setting - measuring – lifting
• Integrated in the drive unit: manual height adjustment of pickup within a range of 50 mm
  (1.969 in)
• Is a skidless pick-up required for transverse tracing?
  No problem for PGK 120
• Lateral vertical tracing? Of course!
• Suitable pick-ups – optical and mechanical type – for any measuring task
• No tools required for exchanging pick-ups
• Swiveling on the measuring stand easily
