Surface Roughness Metrology Instrument

A surface roughness tester uses a probe to contact the measured surface, records the microscopic height variations, and converts them into electrical signals to calculate parameters such as the arithmetic mean deviation of the profile (Ra). It is used to detect the uniformity of paper coatings, the smoothness of plastic films, and the flatness of printing plates, ensuring that the surface quality of products meets usage requirements.
Selection
When selecting, consider whether the measurement range covers the sample's roughness values, whether the probe material is suitable for the hardness of the surface to be measured, and whether the resolution matches the accuracy requirements. Check if the instrument complies with industry standards such as GB/T, and be mindful of the impact of environmental vibrations on contact-based measurements. Choose between portable and benchtop models based on the intended usage scenario.
