MarSurf Pocket Surf IV Mobile roughness measuring instrument
EN
  • Durable cast aluminum housing to provide years of accurate and reliable surface finish gaging
  • Can be used to measure any one of four, selectable, parameters: Ra, Ry, Rmax, Rz
  • Review any of the parameters after the measurement is complete
  • Selectable traverse length 1, 3 or 5 cut-offs of 0.8 mm/0.030“
  • Operates in any position – horizontal, vertical, and upside down
  • Four switchable probe positions – axial (folded) or at 90°, 180° or 270°
  • Even difficult to reach surfaces such as inside and outside diameters are accessible
  • MarConnect data output for easy SPC processing that is compatible with the most common data processing systems
  • Easy to read LCD readout presents the measured roughness value, in micro inches or micrometers, within half a second after the surface is traversed
  • Out of range (high or low) and 'low battery' signals are displayed
  • Improved digital calibration process eliminates scandrivers and potentiometers to simplify and enhance the calibration process
  • Improved battery life with standard 9V battery
  • Technical data
  • Applications
