The surface roughness gauge RTR-1000 from Starr Instruments is suitable for most users with a range of general testing requirements.
Surface roughness testing has many purposes which include; workshop QC, production testing and maintenance check testing of raw and machined parts. The reason for checking the roughness of surfaces is that rough surfaces can wear more quickly and smoother surfaces are more expensive to produce. So depending on your requirements, you need to know when the surface is within acceptable specification tolerances.
A good example of practical use is with the maintaining and repairing rail tracks. If the track surface is too rough it can lead to excessive wear and noise, causing more frequent maintenance. If the track surface too smooth, then that is expensive to produce and also has the additional problem that it can be very difficult for a train to start moving or stop.
Another example of use is in machine shops to check prepared surfaces of components. Visual scans of a surface are not able to determine roughness, just because the surface is shiny, does not mean it has a low roughness.
The RTR-1000 is a surface profilometer designed with a protruding stylus that allows it to be usable on curved and more difficult areas to access surfaces, such as recessed or stepped areas. Examples include the inside automotive cylinder bores and water jackets or o-ring grooves.
