Roughness Tester Machine – Accurate Surface Finish Measurement for Quality Assurance

A Roughness Tester Machine is a non-destructive testing instrument used to evaluate the surface texture or roughness of a material. It measures surface irregularities, deviations, or inconsistencies—key indicators of product quality—by calculating parameters like Ra, Rz, Rq, and Rt.

Modern testers come with touchscreen interfaces, built-in printers, data storage, USB/Bluetooth connectivity, and automatic calibration. These machines are critical in ensuring that parts meet engineering specifications, especially in industries where friction, wear, or lubrication play a significant role.

How to Use a Roughness Tester

  1. Clean the test surface to remove dust or oil.
  2. Power on the tester and select the appropriate measuring parameter (Ra, Rz, etc.).
  3. Position the probe or stylus gently on the surface area.
  4. Initiate the test – the stylus moves over the surface and records the profile.
  5. View results on the digital display and optionally print or export via USB/Bluetooth.
  6. Compare data with required specifications to assess compliance.
