Surface Roughness Tester

Our Surface Roughness Tester RT-8100 is a handheld device designed to provide accurate and reliable surface finish measurements for industrial and laboratory applications. Built with advanced sensor technology, it measures key roughness parameters like Ra, Rq (0.05–15.0 µm) and Rz, Rt (0.1–50 µm), making it suitable for a wide range of materials and surfaces. The device features selectable sampling lengths (0.25, 0.80, 2.50 mm) and evaluation lengths (1.25, 4.0 mm) to match various testing requirements. With a tip arc radius of 10 µm ±1 µm and high accuracy (±15%), the RT-8100 ensures consistent and repeatable results (R < 12%). Its compact design (106 x 70 x 24 mm) and lightweight build (200 g) make it ideal for on-site and mobile testing. Powered by a rechargeable 3.7V lithium-ion battery, it offers convenience, efficiency, and durability in everyday surface measurement tasks.
