A&D Weighing GF-303AN Apollo Precision Balance, NTEP, 320 g x 0.001 g

Yes. The GF-303AN is an NTEP and Measurement Canada Class II approved precision balance. It provides 0.001 g (1 mg) displayed readability, with a 0.01 g verified scale division (e) for its legal-for-trade configuration. This makes it a strong option for businesses that need highly precise measurements along with an approved instrument for commercial weighing. Local weights-and-measures requirements still apply before placing the balance into legal-for-trade service.

The GF-303AN combines a 320 g maximum capacity with 0.001 g (1 mg) readability, allowing it to detect very small changes in sample weight. A&D specifies 0.001 g repeatability and ±0.002 g linearity, making the balance well suited for formulation, quality control, sample preparation, jewelry, laboratory testing, and other applications requiring milligram-level measurements.

The GF-303AN uses external calibration, meaning sensitivity adjustment is performed with an appropriate external calibration weight. This can be particularly useful for facilities that already maintain certified or traceable reference weights as part of their quality procedures. Buyers who specifically want built-in calibration can compare it with the GX-303AN, which uses internal calibration.

The GF-303AN includes a 3.6-inch-high breeze break to help shield the weighing pan from air movement. At the balance's fine 0.001 g readability, drafts and airflow can affect measurement stability, particularly when weighing lightweight samples. The breeze break therefore helps create more consistent conditions for precision weighing.

Yes. The GF-303AN includes USB and RS-232C communication interfaces, allowing weighing results to be transferred to compatible computers, printers, and other data-recording equipment. This can reduce manual transcription and simplify electronic recordkeeping in laboratory, quality-control, production, and commercial workflows. The balance also supports functions including counting, percentage weighing, dynamic/animal weighing, density determination, statistics, and underhook weighing.
