The 4.5.4 SF is a rugged CMM that is ideal for machine shops and manufacturing cells. It features advanced thermal compensation, covered ways, built-in vibration resistance, a shop-hardened design, and optional analog contact scanning. Its most notable feature is its flexibility. The 4.5.4 SF uses standard 110/220 volt outlets with no need for shop air. Its compact footprint and roll-around stand, specifically designed to fit through a standard door, lets you easily move the SF series anywhere in the shop where precise dimensional inspection is required.
