Features & Benefits

  • A portable device operating on the inductive principle to measure the roughness of a wide variety of surfaces.

  • This instrument consists of a processing unit with digital display of the current parameters, and a mobile measurement head which is fitted with a retractable diamond stylus sensor, (5µm / 0.2mils radius), and a working load of 4mN.

  • The roughness profiles are determined by motorised travel of the sensor over the surface to be tested.

  • Each unit is supplied with roughness reference standard, case, tools and mains adapter.

  • Parameters available include:·A1, A2, mr, Mr1, Mr2, Pc, R3z, Ra, Rk, Rp, Rpk, Rq, Rt, Rvk, Ry, Rz, S, Sm and Vo.

Surface Profile
The proper and effective preparation of a surface prior to coating is essential. Making sure that the correct roughness – or profile – has been generated is essential. If the profile is too low, the adhesion of the coating to the surface will be reduced. Too high and there is the danger that the profile peaks will remain uncoated – allowing rust spots to occur.
