Surface Roughness Tester RTD-200 by Starr Instruments is designed for users that have a wide range of surface testing requirements.
The RTD-200 is a contact type surface roughness meter which uses a skidded, diamond-tip stylus that traces across the test surface. The test force is a very low 4mN to ensure ultra sensitivity and measurement accuracy
It features multiple test parameters and adjustable setting options for thorough testing. Users can also store up to 100 test results including wave form graphs and conversion value to other parameters. These can be reviewed or downloaded for interpretation using the included DataView software program (available as a download).
Commonly utilized to test in a work shop or laboratory, the RTD-200 is used to determine the roughness profile of surface finishes, both raw and machined. It is important to measure quality and manage manufacturing processes for consistency and fit for purpose. If a surface is too rough it can wear out more quickly as it has a higher co-efficient of friction. To make a surface smoother it can be much more expensive, so a balance between wear costs and production costs by analysing the data from surface roughness tests.
The Starr RTD-200 is also suitable for curved surfaces by having a protruding stylus, and the bright OLED dot matrix screen is easy to read in daylight or low light. The software is used for management of data including graphing of results.
