The portable surface roughness tester SR220 is a small portable instrument with large OLED display, high precision and various parameters. It can be used in the laboratory, in the inspection area or anywhere where on-site surface roughness testing is required. The measurement data from the SR220 can be output to a PC or micro-printer.
