TIME® 3110 Pocket Surface Roughness Tester

Product Code: TIME-3110

TIME 3110 (TR110) is a handheld surface roughness tester for Ra, Rz measurement. It is economically priced and well suited for various mechanical manufacturing processes.

This gauge features an easy to read backlit LCD display allowing users to view result from any angle. The case provides durability and the size is compact for portability.  TIME 3110 features an integral probe that drops down from underneath the unit, making it most suitable for large, flat surfaces or wide curves where there is ample space to position the device stably.

The unit is easy to operate and can be calibrated using the included reference specimen. The sensitive probe traces the surface and converts the measurements into Ra or Rz.  The measuring range for Ra is 0.05µm - 10.0µm and Rz is 0.1µm - 50µm.
