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 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.
