Advanced portable roughness tester

This portable surface roughness tester measure multiple roughness parameters with a 1-button click.

Roughness measurement parameters such as Ra, Rz, Rp, Rv and Rt are displayed on a brightly lit intuitive 2.4" LCD colour display.

Its rechargeable battery operation makes it a convenient way of performing fast, easy and precise on-the-spot measurements in almost any environment and surface.

The hard-wearing diamond stylus is drawn across the part with a precision motorised traverse mechanism to ensure that the correct horizontal distance is travelled.

Vertical movement of the stylus is detected by a highquality piezo-electric pick-up as it travels across peaks and valleys which converts mechanical movement into electrical signals.

The electrical signal is digitised and sent to a microprocessor for instant calculation of surface parameters using standardised algorithms.

Standards and traceability

The reference standard supplied can be used both to calibrate the instrument and check for stylus wear to ensure the most accurate results are always being achieved.
