A&D Weighing GF-123AN Apollo Precision Balance, NTEP, 120 g x 0.001 g

Yes. The GF-123AN 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 combination is useful for businesses that require high-resolution measurements along with an approved weighing instrument for commercial applications. Local weights-and-measures requirements may still apply before the balance is placed into legal-for-trade service.

The GF-123AN combines a 120 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 suitable for formulation, sample preparation, quality control, laboratory testing, jewelry-related measurements, and other applications requiring milligram-level precision.

The GF-123AN uses external calibration, meaning sensitivity adjustment is performed with an appropriate external reference weight rather than a built-in calibration weight. A&D specifies 50 g and 100 g external calibration weights for this platform. This design can be a good fit for facilities that already maintain certified or traceable reference weights as part of their quality-control procedures.

The GF-123AN includes a 3.6-inch-high breeze break to help shield the weighing pan from drafts and surrounding air movement. This is particularly useful when working at 0.001 g readability, where even small air currents can make sensitive measurements less stable. The breeze break helps create more consistent weighing conditions for small and lightweight samples.

Yes. The GF-123AN includes USB and RS-232C connectivity, allowing weighing results to be transferred to compatible computers and other data-collection equipment. This can reduce manual transcription and make electronic recordkeeping easier in laboratory, quality-control, production, and commercial workflows.
