QR Series Surface Roughness Measurement Instruments Introduction: The QR Series Surface Roughness Measurement Instruments utilize non-contact roughness sensor technology, with precision guideways as the measurement reference. Featuring high accuracy and broad applicability, they effortlessly handle roughness measurements on complex surfaces such as inclined parts and curved parts. The measurement principle employs the stylus method: the sensor's stylus slides over the measured surface, detecting microscopic surface irregularities and generating displacement. This displacement is converted into an electrical signal by a high-precision inductive sensor, which is then processed, filtered, and calculated to determine the surface roughness parameter values.
