Jul 01, 2010 Featuring automated motorized operation and joystick control, MarSurf® UD 120 has magnetic probe mounting feature that not only prevents probe damage, but allows probe changes in seconds, without additional tools. Probe offers measuring range of 10-20 mm, while drive unit allows traversing lengths from 0.1-120 mm with drive speeds from 0.1-2 mm/s. Probe's motion is sensed by optical measuring system based on rocker-arm principal with stylus tip on one end and interferometer on other.
