The Mettler Toledo® JE1103C/A Carat Balance is a premier, high-capacity precision scale meticulously engineered for master gemologists, busy diamond brokers, and bulk gemstone wholesalers. Offering an expansive maximum capacity of 1,100 carats (220 grams), this balance accommodates large gemstone parcels and multi-stone sorting trays with ease. It features an ultra-fine analytical resolution of 0.001 carats (0.1 mg) powered by an advanced Electromagnetic Force Compensation (EMFC) weighing cell. Housed in a rigid die-cast aluminum base with a stainless steel 90 mm weighing pan, the unit sits heavy on the countertop to absorb ambient storefront vibrations and ensure fast, 2-second measurement stabilization.

Designed for maximum operational uptime in commercial counter spaces, the JE1103C/A replaces the complexity of modern touchscreens with a highly reliable, angled backlit LCD display featuring oversized digits for effortless readability under intense showroom spotlights. Legal-for-trade certification ensures full compliance with local weights and measures laws, while an internal adjustment feature allows showroom staff to instantly test and recalibrate the balance at the press of a single button without touching loose physical calibration weights. Additionally, its dual-power flexibility—capable of running on either a standard AC wall adapter or four AA batteries—makes this elite balance uniquely portable for secure on-the-go asset evaluations, trade shows, and estate purchasing events.
