The Hommel-Etamic W20 skidless probe system has been designed specifically for mobile roughness measurement. It not only measures all common roughness parameters, but also evaluates the waviness and total profile of your surface. The measuring instrument is particularly compact and portable. The built-in battery means that the device can be used even without an external power supply.

The measuring probe is automatically positioned on the surface. The motorized probe lowering function simplifies operation — you simply need to position the traverse unit and start the measurement. On completion of the measurement, the probe arm lifts up from the surface automatically. This protects the probe tip from damage.

The large color touchscreen is extremely clear to read and easy to operate. With the integrated printer, you can display your measurement results in graph form immediately. Parameters, profile graphics, Abbott curves and statistical data also can be displayed. The measuring instrument offers seven measuring programs, as well as the option to test with the integrated roughness standard.
