Mahr/Federal Pocket Surf IV Portable Surface Roughness Gage w/ .0004" Radius Probe

A pocket-sized economically priced, completely portable instrument which performs traceable surface roughness measurements on a wide variety of surfaces; can be used confidently in production, on the shop floor and in the laboratory.


  • Solidly built, with a durable cast aluminum housing, to provide years of accurate, reliable surface finish gaging
  • Can be used to measure any one of four, switch selectable, parameters:
    Ra - Average roughness
    Rmax/Ry - Max/Min Roughness Depth (DiN)
  • Then 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 com-mon data processing systems
  • Easy-to-read LCD readout pre-sents the measured roughness value, in microinches or micro-meters, within half a second after the surface is traversed.
  • Out-of-range (high or low) and "battery low" signals are also displayed
  • Improved digital calibration pro-cess eliminate screwdrivers and potentiometers to simplify and enhance the calibration process
  • Improved battery life with easy to replace standard 9V battery
  • Built in digital output.
  • Supplied with general purpose probe. For most surface roughness applications. Has a 90° conical diamond stylus.
