A linear roughness measurement is available via surface roughness testers. To do this, a mechanical tip is used to quantify the roughness of a surface along an arbitrary line. Manual touch procedures may be substituted by last, photonic, and other testing processes as equipment becomes more sophisticated for quicker and more streamlined results. To determine which surface roughness testing system would be the best choice for your testing requirements, get in touch with one of our qualified consultants right away.

Ra, the average absolute deviation from a surface’s centre line, is the standard unit used to express surface roughness values. The Rq, which is the mean root square of the deviation, is one of the additional values. Depending on your unique needs, there are a plethora of alternative testing scales. More testing scale options might be available with a more sophisticated surface roughness tester.

After the test, the data gathering system is processed using digital filtering, and a DSP chip is used to calculate the parameters. The parameter results can then be read on an LCD screen or simply printed out and sent to a PC.
