Rugosímetro TR-110

Teste de Rugosidade de Superfícies – portátil – TR-110

Portable surface roughness tester for determining surface texture, combining measurement of roughness parameters Ra and Rz in one instrument.The compact portable TR-110 roughness tester is designed for fast and precise measurement. It employs a piezoelectric microsensor technique which is identical to that of high-precision laboratory roughness testers. The outstanding features of the TR-110 include user-friendly operation and a high repeating accuracy.Simply press a button and within seconds, a microsensor in the form of a diamond stylus scans the surface. Depending on the pre-set cut-off length, the digital display shows either the roughness parameter Rz or Ra (see also DIN 4762, 4768, 4775, ISO 4288.)The TR-110 roughness tester can determine both parameters (Ra and Rz) in one surface scan. An integrated sleeve can be slid over the sensor tip in order to protect the TR-110™ during periods of non-use. In addition to this, an automatic 1.5 minute switch-off function protects the lithium-ion battery against unnecessary discharge.
  • Roughness Parameters
Ra = arithmetical mean roughness value
Ra, signifying the roughness parameter, is a value that is recognised and used internationally. It denotes the arithmetical mean value of the absolute values of the profile deviations within the sample area. The numerical value of Ra is always smaller than the Rz reading derived from the same sample.Rz = mean roughness depth (peak to valley)
Rz denotes the mean roughness depth, i.e. the arithmetical mean of the highest single measurements of several single adjacent tracing sections.
