The Mettler Toledo JE155DUG/00 Gold Balance is a high-precision semi-microbalance specifically engineered for jewelers, gemologists, and precious metal traders who require extreme precision. As a dual-range instrument, it allows users to weigh fine gold, diamonds, and intricate jewelry pieces down to five decimal places 0.01mg in its fine range, switching automatically to a 0.1 mg readability for heavier items. Built with a robust die-cast aluminum base and a stainless steel weighing pan, it is designed to withstand the fast-paced, demanding environment of a retail jewelry shop or production workshop while keeping bench space to a minimum.
This model sets itself apart by blending advanced laboratory-grade accuracy with user-friendly features tailored for the trade. It simplifies daily quality control via a built-in internal adjustment function, allowing users to test and calibrate the balance at the press of a button without external weights. Additionally, the JE155DUG/00 features an intuitive interface with 16 toggleable weight units—including carats, grams, pennyweights, and troy ounces—and supports an optional density kit to easily calculate the purity of small precious samples.
