Product Description

The Elcometer 7062 MarSurf PS10 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 MarSurf PS10 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 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.

The Features of the Elcometer 7062 MarSurf PS10 Surface Roughness Tester

• 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 diamond stylus tip with a measuring force of 0.7 mN. Different stylus’ are available for various applications.

• ASTM D7127
• ASME B46
• DIN 4768*
• EN 10049
• ISO 4287
• ISO 4287/1*

Test Method

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 several measurement parameters including:

Rmax: The greatest distance between the highest peak and lowest valley over the sampling length.

Ra: The average surface roughness over the sampling length.

Rt: The distance between the highest peak and the lowest valley within any given sampling length.

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