Digital Roughness Tester

The digital roughness tester moves a probe across the material surface, converting height variations into electrical signals. These signals are processed to display the arithmetic mean deviation of the profile. It is used to measure microscopic irregularities on object surfaces and finds applications in testing coating adhesion and detecting the smoothness of printing paper.
Selection
When selecting, consider that the measurement range should cover the fluctuation level of the sample to be tested, the probe material should be suitable for the hardness of the measured surface, and the resolution should match the accuracy requirements. The environmental adaptability should meet workshop or laboratory conditions, and the calibration method should comply with industry standards.
