A&D Weighing GF-403AN Apollo Precision Balance, NTEP, 420 g x 0.001 g

Yes. The GF-403AN is an NTEP and Measurement Canada Class II approved precision balance. It offers 0.001 g (1 mg) displayed readability, while the verified scale division (e) is 0.01 g for its approved legal-for-trade configuration. This makes it especially useful when a business needs high-resolution measurements combined with an approved instrument for commercial weighing. Local weights-and-measures requirements still apply when placing the balance into legal-for-trade service.

The GF-403AN combines a 420 g maximum capacity with 0.001 g (1 mg) readability. It provides 0.001 g repeatability and ±0.002 g linearity, making it suitable for formulation, sample preparation, quality control, production testing, and other applications where very small differences in weight need to be detected reliably.

The GF-403AN uses external calibration, so sensitivity adjustment is performed using an appropriate external calibration weight. This can be a good choice for laboratories and businesses that already maintain certified or traceable reference weights as part of their quality procedures. Customers who prefer built-in calibration can compare it with the GX-403AN, which uses internal calibration.

Yes. A&D lists the GF-403AN with a 3.6-inch-high breeze break. At a fine 0.001 g readability, air movement around the weighing pan can influence measurement stability, so the breeze break helps shield samples from drafts and supports more consistent weighing conditions. This can be particularly useful when weighing small or lightweight samples.

Yes. The GF-403AN includes USB and RS-232C connectivity, allowing weighing data to be transferred to compatible computers and other equipment. This can reduce manual transcription and simplify electronic recordkeeping in laboratory, quality-control, production, and commercial workflows. A&D also supports additional connectivity options, including an optional Bluetooth accessory.
