A&D Weighing GX-603AN Apollo Precision Balance with Internal Calibration, NTEP, 620 g x 0.001 g

Yes. The GX-603AN is an NTEP-approved Class II precision balance designed for applications requiring legal-for-trade capability. It provides 0.001 g (1 mg) displayed readability, while its verified scale division (e) is 0.01 g in the approved configuration. This combination is useful for businesses that need very fine measurement resolution along with an approved commercial weighing instrument. Local weights-and-measures requirements may still apply before the balance is placed into legal-for-trade service.

The GX-603AN combines a 620 g maximum capacity with 0.001 g (1 mg) readability. A&D specifies 0.001 g repeatability and ±0.002 g linearity, making the balance well suited for formulation, sample preparation, quality control, laboratory testing, production, and other applications where small changes in mass need to be measured reliably.

Yes. The GX-603AN uses A&D's internal calibration system, allowing sensitivity adjustment with a built-in calibration mechanism instead of requiring the operator to manually place an external calibration weight on the pan. This can simplify routine calibration and is especially useful in laboratories and quality-controlled environments where maintaining consistent weighing performance is important.

The GX-603AN includes a 3.6-inch-high breeze break to help protect the weighing area from drafts and surrounding air movement. This is particularly valuable at the balance's fine 0.001 g readability, where even small air currents can affect measurement stability. The breeze break therefore helps provide more consistent weighing conditions for small and lightweight samples.

Yes. The GX-603AN provides USB and RS-232C communication interfaces for connection to compatible computers, printers, and other data-collection equipment. This can reduce manual transcription and make electronic recordkeeping easier in laboratory, production, quality-control, and commercial workflows.
