Made of quality steel, the TQC Sheen surface roughness tester comes in its own leather pouch for ease of transport. It Indicates the surface condition of blasted steel according to ISO 8503 in grades of fine, medium, and coarse, allowing for comparison in the lab or on the go.
It is possible to test the roughness of blast-cleaned steel using this grit-blast and shot-blast surface profile comparison measuring tool.
The roughness surface of steel can play an important part in its suitability for a range of uses, especially when it comes to engineering applications. Surface roughness testing can also determine how your steel surfaces will interact with their environment and which paints and coatings may be most suitable.
Using surface roughness testers like this TQC Sheen model is easy. Simply place the appropriate comparator (G for Grit, S for Shot) against a blast cleaned surface. The finish can be compared against the four sections of the comparator. It is then a simple matter to identify (by sight and touch) the standard surface:
This surface roughness tester is made from high purity nickel and has been designed to help you comply with a range of internationally recognized testing standards, including STM D4417 Method A, ISO 8503-1 and ISO 8503-2.
The TQC Sheen Steel Surface Roughness Comparator is a manual tool. If you would prefer a digital gage for assessing the roughness of your steel surfaces, you may be interested in the TQC Sheen Surface Roughness Gauge.
