The Mettler Toledo® JET1603C/A Carat Balance delivers the highest capacity in its class, specifically engineered to meet the demands of large-scale diamond wholesalers, precious gemstone importers, and busy jewelry manufacturing laboratories. This elite legal-for-trade instrument boasts an expanded weighing capacity of 320 grams, offering an ultra-precise dual-range configuration with an analytical readability of 0.1 milligrams (0.0001 g) alongside its standard certified trade resolution of 1 milligram (0.001 g). Built with a heavy-duty metal base and an aluminum die-cast housing, it features an integrated glass draft shield to isolate the weighing pan, ensuring rapid stabilization and accurate measurements free from retail or lab air currents.
Operating this premium balance is fast and intuitive via a 4.5-inch color TFT touchscreen display that remains clear and sharp under intense commercial spotlighting. To safeguard financial transactions and maintain strict weights and measures compliance, the JET1603C/A features Fully Automatic Calibration Technology (FACT) to perform automatic internal calibrations whenever environmental temperature changes are detected. It also serves as a central hub for business operations, equipped with an advanced communications suite—including RS232, a USB Host, and a USB Device port—to cleanly export data to inventory computers, barcode scanners, and customer-facing auxiliary displays.
