A&D FX-300iN Legal for Trade Diamond Scale

Weigh diamonds, coloured stones and small precious metal work at the bench to 320 g or 1600 ct, reading down to 0.001 g and 0.005 ct. The A&D FX-300iN is a legal-for-trade precision scale for jewelry and diamond work, supporting carats, pennyweights, troy ounces and a wide range of further units alongside parts counting and percent weighing. Functions and active units are user-selectable, so the display shows only what you need, and as a legal-for-trade model the scale is factory calibrated and does not permit user calibration.
