Because of its compact size and front-loading design, the Vibra Carat Balance takes up only half the space of conventional carat scales. Its revolutionary tuning fork sensor provides greater stability than scales with electromagnetic sensors. High resolution, quick response, high stability, light weight, and compact size are all made possible by the use of the patent-pending mono-metal tuning-fork sensor. This innovative technology provides greater accuracy than in balances using load cells and greater stability than electro-magnetic balances. Combine this technology with attractive styling, a built-in RS232C interface, and affordable prices and you get the Vibra CT-600NT carat balance.
