Product Features  
  • New, high-resolution CMOS matrix camera with a large 40 x 24 mm live image field allows fast scanning with over 120 images per second
  • High precision when measuring diameters and lengths
  • Extremely fast measuring times thanks to high measuring speeds of up to 200 mm / s
  • By using Mahr’s MarWin software platform, you can benefit from our decades of experience in length, shape, position and contour measurement
  • Excellent entry level price into the small optical shaft measuring machine segment
MarWin EasyShaft Software V9.0
  • The familiar Windows® user interface makes for a short learning curve
  • The EasyShaft user interface is in line with the standard user interface across all Mahr products (cf. EasyForm or Contour 1)
  • Clear, windows-based layout
  • User-friendly, 100% touchscreen functionality
  • Predefined macros for easy programming (e.g. diameter measurement at the touch of a single button)
  • Many functions can be selected directly via obvious icons
  • Touchscreen-controllable machine axes
  • The live image from the matrix camera is continuously displayed during measurement, i.e. direct visual assessment of the workpiece surface (e.g. soiling) even during measurement
  • For individual and series measurements: the ideal operating strategy for every task
  • User-friendly, state-of-the-art measuring program management
  • Time-optimized measuring program sequence, thus minimal measuring times
  • Clear measuring records – in black-and-white or color – output to all Windows® printers
  • Future-proof investment, runs under Windows® 7 Ultimate
  • Optional data export to statistics programs extends the range of functions of the EasyShaft software
