A&D Weighing GF-603AN Apollo Precision Balance, NTEP, 620 g x 0.001 g

Yes. The GF-603AN is an NTEP and Measurement Canada Class II approved precision balance. It offers a fine 0.001 g (1 mg) displayed readability, while its verified scale division (e) is 0.01 g for the applicable legal-for-trade configuration. This makes it useful for businesses that require high-resolution measurements along 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-603AN combines a 620 g maximum capacity with 0.001 g (1 mg) readability, allowing users to detect very small changes in sample weight. It provides 0.001 g repeatability and ±0.002 g linearity, making it well suited for formulation, quality control, sample preparation, production testing, and other applications requiring milligram-level precision.

The GF-603AN uses external calibration, meaning sensitivity adjustment is performed using an appropriate external calibration weight. This can be a good fit 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 consider the GX-603AN, A&D's internally calibrated counterpart.

The GF-603AN is designed to combine milligram-level precision with fast response. A&D specifies an approximate 1-second stabilization time, including approximately 0.8 seconds with a 5 g load under suitable conditions. This quick response can improve efficiency when operators perform repeated measurements in laboratory, production, quality-control, or commercial workflows.

Yes. The GF-603AN includes USB and RS-232C communication interfaces, allowing weighing results to be transferred to compatible computers, printers, and other equipment. This can reduce manual data entry and simplify electronic recordkeeping. The balance also supports applications including parts counting, percentage weighing, animal/dynamic weighing, density determination, statistics, and underhook weighing.
