Elcometer 7062 MarSurf PS10 Surface Roughness Tester

The Elcometer 7062 surface roughness tester is a light weight and portable measuring solution for the range of surface roughness measurements required for compliance to International Standards.

In protective coating applications there is a requirement to measure surface roughness.

With 31 surface parameter settings available the Elcometer 7062 surface roughness tester can display all parameters that comply to National & International Standards.

These values include peak-to-valley profile measurement in combination with an assessment of the frequency of peaks within the sample area.

The Elcometer 7062 surface roughess tester is a light weight and portable measuring solution for the range of surface roughness measurements required for compliance to International Standards.

The unit is also suitable for assessing surface roughness conditions in a wide range of general industrial applications; particularly where the sample is too large to bring to the laboratory.

  • Multi-Lingual Display: All the required information is displayed on screen in a choice of 17 languages.
  • Flexible: Can be used in virtually any position; horizontally, vertically, upside down. A height adjustment accessory to accommodate various sample sizes is supplied with each gauge as standard.
  • Integrated Calibration Standard: No external calibration standard is required; provides greater ease of use.
  • Removable Drive Unit: Drive unit can be removed from main unit and used with an extension cable (included) to allow for measurement in hard to reach areas.
  • Stylus pick-up with removable protection: 2µm (80µin) diamond stylus tip with a measuring force of 0.7 mN. Different stylus’ are available for various applications.


How to use a surface roughness tester

Surface roughness testers consist of a stylus which is mechanically drawn across the surface recording an 'image' of the surface roughness across a pre-defined sample length.  The measurement technique provides a number of measurement parameters including:

Rmax: The largest difference between peaks & valleys in an individual sampling length within the overall evaluation length

Ra: The average roughness over the sampling length.

Rt: The distance between the highest peak and lowest valley over the evaluation length

Rz: The average distance between the highest peak and lowest valley over a number of sampling lengths
