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.
