The Mettler Toledo® JET1103C/A Carat Balance is an exceptional, high-capacity jewelry instrument engineered to deliver elite precision for diamond wholesalers, gemstone traders, and luxury retail showrooms. Combining an extended maximum capacity of 220 grams with legal-for-trade certification, this dual-range balance provides an ultra-fine analytical readability of 0.1 milligrams (0.0001 g) alongside its certified commercial resolution of 1 milligram (0.001 g). Its premium build includes a rigid metal base, an impact-resistant die-cast aluminum housing, and a dedicated glass draft shield that creates a perfectly stable environment for isolating and securing sensitive micro-weight evaluations.
User navigation is streamlined through a crisp 4.5-inch color TFT touchscreen interface that presents data with high legibility, even under the intense spotlighting of commercial counter spaces. To eliminate the downtime of manual maintenance and protect transactional legality, the JET1103C/A relies on Fully Automatic Calibration Technology (FACT) to perform autonomous internal balance calibrations whenever ambient room temperatures shift. The unit is optimized for modern point-of-sale systems, containing an integrated communications matrix featuring built-in RS232, a USB Host, and a USB Device port to securely sync auxiliary customer-facing displays, PC inventory software, and ticket printers.
