    Surface roughness is typically characterized by parameters such as Ra (arithmetical mean roughness), Rz (maximum peak-to-valley height), Rq (root mean square roughness), and Rt (total roughness). These parameters describe different aspects of the surface profile and provide insights into the smoothness or roughness of the surface.


    • Small in size, light in weight and easy to use.
    • Highly sophisticated inductance sensor.
    • Built-in lithium-ion rechargeable battery and control circuit with high capacity.
    • Use RS-232 data output to connect with PC and provide bluetooth data output choice.

    Tips: What are the Advantages of Surface Roughness Tester?

    • Quality control. Surface roughness is an important parameter in many industries, including manufacturing, automotive, aerospace, and engineering. A surface roughness tester enables precise and reliable measurement of surface roughness, ensuring that products meet the desired quality standards.
    • Objective measurements. Surface roughness testers provide objective and quantifiable measurements of surface roughness, eliminating subjectivity and variations that may occur when relying on visual inspection or touch. This ensures consistency in measurements and allows for easy comparison between different surfaces or batches of products.
    • Process optimization. By measuring and analyzing surface roughness, manufacturers can gain insights into the performance and characteristics of their products. This information can be used to optimize manufacturing processes, improve product design, and enhance product performance.
