A&D Weighing GX-203AN Apollo Precision Balance with Internal Calibration, NTEP, Class II, 220 g x 0.001 g

Yes. The GX-203AN is an NTEP-approved Class II precision balance designed for applicable legal-for-trade weighing applications. It provides 0.001 g (1 mg) displayed readability, while the approved verification interval (e) is 0.01 g. This makes it a useful choice for businesses that need high-resolution measurements together with an approved commercial weighing instrument. Local weights-and-measures requirements still apply before placing the balance into legal-for-trade service.

The GX-203AN combines a 220 g maximum capacity with 0.001 g (1 mg) readability. Published specifications list 0.001 g repeatability and ±0.002 g linearity, allowing the balance to detect very small changes in sample mass. This makes it well suited for formulation, sample preparation, quality control, laboratory testing, production, and other applications requiring reliable milligram-level measurements.

Yes. The GX-203AN features internal calibration (ASC), so sensitivity adjustment can be performed using its built-in calibration mechanism instead of requiring the operator to manually place an external calibration weight on the pan for routine calibration. This can simplify calibration procedures and is particularly useful in laboratories and quality-controlled environments where consistent weighing performance is important.

The GX-203AN includes a 3.6-inch-high breeze break to help protect the weighing area from drafts and surrounding air movement. This is particularly useful at 0.001 g readability, where even minor airflow can influence measurement stability. The breeze break therefore helps create more consistent weighing conditions when working with small or lightweight samples.

Yes. The GX-203AN provides USB and RS-232C communication interfaces, allowing weighing results to be transferred to compatible computers and other data-collection equipment. This can reduce manual transcription and improve electronic recordkeeping. The balance also supports applications including parts counting, percentage weighing, animal/dynamic weighing, density determination, statistical calculations, and underhook weighing.
