The roughness tester Hommel Etamic W10 is a portable instrument for measuring roughness. The roughness tester measures all common roughness variables according to international standards such as DIN EN ISO or ISO MOTIF. Furthermore, the surface roughness tester is mains power independent, because it is battery powered. It features a wireless feed, which makes it very flexible for applications in practical operation. The button can be swiveled by 90 °, thereby with the roughness meter overhead measurements can take place in a vertical position or a transverse scan. The roughness tester is operated with a modern 4.3'' touch screen, which simultaneously immediately displays a tolerance rating and surface profiles. These measurement results can be printed directly via an integrated thermal printer, making immediate documentation possible. This roughness tester has 8 possible measurement programs, of which a monitoring program is specially designed for equipment verification. Here an integrated roughness standard and setpoints are stored, so that the device can be checked on the spot. Optionally,evaluation software EVOVIS can be purchased for the roughness tester equipped with USB and Bluetooth interface,which makes it possible to evaluate identified measured values and save them to a computer.
