Roughness testerThe (portable) TR240 can measure the surface roughness of various machined parts. According to the selected measurement conditions, the corresponding parameters of the computer are displayed clearly on the LCD display, and all measurement results and graphics can be output on the printer or communicate with a PC. Surface sensors can be optionally used to measure surfaces, small hole sensors to measure inner hole walls, and groove/deep groove sensors to measure the roughness of groove bottoms or steps.
