TR200 Plus Digital Roughness Tester for Industrial Surface Finish Inspection

This portable surface roughness tester features an integrated process, dual OLED display and sensor, and allows for user selectable roughness units in Ra or Rz

Ideal for On-Site Surface Finish Inspection and Quality Control

This portable surface roughness tester is designed for fast, reliable surface finish measurement directly on the shop floor or in the field. With an integrated probe and control unit, plus a clear dual OLED display, it delivers accurate Ra and Rz readings without the need for bulky benchtop systems. It is well suited for machining, metalworking, automotive parts inspection, aerospace components, and general manufacturing quality control.

The Portable Surface Roughness Tester TR200 is used by quality control technicians, machinists, and maintenance professionals to measure detailed surface finish parameters on metals, plastics, and machined components. Portable roughness testers provide standardized Ra, Rz, and other surface profile values that help manufacturers verify machining quality and confirm that components meet design specifications.

Professionals value the TR200 for its higher‑resolution measurements, intuitive interface, and compact design that support on‑site surface evaluation without transporting parts to a metrology lab. Compared with manual comparison charts, this tester delivers precise numerical data that improves quality control workflows in manufacturing, inspection, and maintenance applications.

In addition to flat surfaces, it measures round and sloped planes with precision. The “new model” also supports measurement of grooves and recessions up to 3.1 x 1.2 in (80 x 30 mm), expanding its application range for complex parts and hard-to-reach areas.

20 parameters: Ra, Rz, Ry, Rq, Rt, Rp, Rpc, Rk, Rpk, Rvk, Rv, R3z, R3y, RzJIS, Rsk, Rku, Rsm, Rs, Rmax, Mr1/Mr2
