Detailed

I. Purpose

The surface roughness measuring instrument is suitable for laboratories and production sites. It can measure the surface roughness of various machined parts, including flat surfaces, inclined surfaces, outer cylindrical surfaces, curved surfaces, small holes, grooves and axles, etc., according to the selected measurement The corresponding parameters are calculated according to the conditions, and the measurement results and contour graphics are clearly displayed on the liquid crystal display.
