Surface
roughness tester, can measure the roughness parameters of flat,
inclined, curved and small holes
Surface roughness measuring instrument for laboratory and
production sites, can measure the surface roughness of a variety of
machined parts, including planes, bevels, outer cylindrical
surfaces, curved surfaces, small holes, grooves and axles, etc.,
according to selected measurements Conditions Calculate the
corresponding parameters and clearly display the measurement
results and contour graphs on the LCD.
