Roughness testers

Roughness measurement can be very important on some parts; it can make piece’s operating features change in a very significant way. These instruments are recognised to be efficient in hard-to-reach points’ measurement.

Non-destructive testing instrument used for measuring surface roughness. The possibility to measure different parameters and to set various measurement profiles makes it a highly professional device, suitable to operate both in production and in laboratory. The roughness tester is commonly employed for quality control activities and to check incoming and outgoing goods.
