TR Profile / TR Profile DH-8

TR Profile DH-8 surface measuring instrument trimos

The TR Profile and TR Profile DH-8 are extremely precise surface roughness measuring instruments, built for the use in the workshop and on production lines as well as in the lab.

From the simple roughness measurement without accessories, directly on the machine, to the measurements in the laboratory with measuring support, special tracers and other accessories, including the recording of contours, the TR Profile and TR Profile DH-8 offer maximum flexibility for surface analysis.

The tracers are the core pieces of the roughness meters. They are, to a wide extent, the determining factor of the precision of the measuring values obtained. The great choice of tracers is the result of decades of experience in the construction of such probes. The traversing unit with an integrated reference flat allows to effect precise measurements also with skidless tracers (VHF versions). The traversing units of TR Profile and TR Profile DH-8 are identical.

All instruments can be connected to a PC. They are delivered with a simple analysis software.

  • Linearity and measuring accuracy
  • Application flexibility
  • Large range of accessories
  • Removable traversing units
  • Rechargeable battery for mobile applications
  • Tracers with and without skid
  • Ease of use
