The surface measuring instrument “Surftest SJ-500” from Mitutoyo is an electrical stylus instrument for the determination of all common form and roughness parameters.<\/p>\n

The use of different mechanical probes allows testing in wide fields of application. In addition to roughness measurement, the contour measurement components complete the performance spectrum of this device.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Contour measurement includes the determination of angles, radii, distances and coordinates as well as the computer-controlled target\/actual comparison with measured or calculated profile specifications. In conjunction with versatile evaluation options, this allows statements to be made about the micro- and macro-shape that go well beyond those of conventional roughness measurement variables.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
