When it comes to measuring surfaces for roughness or contour profile the Kosaka Surfcorder SE-1200 instruments has no equal.  Consisting of a combined amplifier printer with a 25mm drive unit and universal pick-up this small compact instrument can carry out many measurements which larger competitive models are needed, such as curved surfaces, short lands, profiles  and very small bores.  Easily programmed via its keypad, selections of traverse distance, cut offs, curved, flat surface, vertical and horizontal magnifications and universal Ra and waveform parameters are quickly set, results witrh  profile graphs being rapidly printed out.  The SE-1200 is shown below with it pick-up  mouinted in a right angle format.
