Surface roughness measurement for sensitive surfaces

Very compact and flexible, but above all extremely precise - the surface roughness tester

The hot-rolled and blasted rough surface (2E) of a 5 mm thick lean duplex steel is ideal for grouting into masonry in the construction industry. However, the same surface is wholly unsuitable for the field of medical technology!
Fast and precise determination of surface roughness in micrometres!
Fast and specific determination of the surface roughness plays a key role in many industries, but particularly in industries subject to stringent hygiene regulations, such as medical technology and the foodstuff industry. These days it is increasingly accepted that the surface quality, and thus the determination of the surface roughness, is necessary to establish the corrosion resistance characteristics of a material.
For example, a rough and badly ground surface on Mat. 1.4404 could result in poorer corrosion resistance characteristics than a surface that is properly ground and smooth, or electropolished on Mat. 1.4301!
This makes it clear that, apart from the material itself, the choice of surface is one of the key selection criteria when it comes to ensuring the correct corrosion resistance characteristics. And it is for this reason that you should always have the surface roughness checked and confirmed in order to ascertain that the surface quality meets your requirements!
This involves the precise scanning of a working section of up to 12.5 mm. This check enables the determination of a range of average roughness values:
arithmetical mean roughness Ra, root mean square roughness Rq, peak-to-valley height Rz, etc. Ask our expert - Wolf-Rüdiger Gottwald (+49 (0) 5225 8799 270).
