Digital Surface Roughness Tester – Ra, Rz, Rq & Multi-Parameter Measurement
Measure surface finish accurately and efficiently with this digital surface roughness tester. Supporting Ra, Rz, Rq and 12+ roughness parameters, it delivers high-resolution results for machining, manufacturing, and quality inspection applications.
This digital surface roughness tester is a high-precision measuring instrument designed for evaluating surface finish across a wide range of machined and processed materials. Using an inductive sensing principle, the device provides reliable and repeatable roughness measurements essential for quality control, process validation, and compliance verification.
The instrument supports Ra, Rz, Rq, and more than 12 additional roughness parameters, making it suitable for advanced surface analysis in accordance with ISO, DIN, ANSI, and JIS standards. A fast ARM-based processor enables rapid data acquisition and real-time display of both numerical results and surface contour graphs on the integrated LCD screen.
With multiple selectable filtering methods, the tester adapts easily to different surface textures and measurement requirements. Its compact handheld design and long battery life make it ideal for both shop-floor inspections and laboratory environments.
