A&D Weighing GF-4002AN Apollo Precision Balance, NTEP, 4200 g x 0.01 g

Yes. The GF-4002AN is an NTEP-approved Class II precision balance designed for legal-for-trade applications. It offers 0.01 g displayed readability, while its verified scale division (e) is 0.1 g in the applicable legal-for-trade configuration. This makes it a practical option for businesses that need precise measurements along with an approved instrument for commercial weighing. Local weights-and-measures requirements may apply before the balance is placed into legal-for-trade service.

The GF-4002AN combines a 4,200 g (4.2 kg) maximum capacity with 0.01 g readability, allowing users to detect changes as small as one-hundredth of a gram. It provides 0.01 g repeatability and ±0.02 g linearity, making it suitable for formulation, production, quality control, inventory, and other applications that require both useful capacity and fine measurement resolution.

The GF-4002AN uses external calibration, meaning sensitivity adjustment is performed using an appropriate external calibration weight. This configuration can be particularly useful for laboratories and businesses that already maintain certified or traceable reference weights as part of their quality procedures. Customers who specifically want built-in calibration can consider the GX-4002AN, which is the internally calibrated counterpart in A&D’s legal-for-trade Apollo lineup.

The GF-4002AN is designed for fast precision weighing, with an approximate 1-second stabilization time under suitable conditions. A&D also specifies approximately 0.8-second stabilization with a 50 g load. This fast response can help improve productivity when operators perform repeated measurements in commercial, laboratory, production, or quality-control workflows.

Yes. The GF-4002AN includes USB and RS-232C communication interfaces, allowing weighing results to be transferred to compatible computers, printers, and other equipment. This can reduce manual transcription and simplify electronic recordkeeping. The balance also supports functions such as parts counting, percentage weighing, animal/dynamic weighing, density determination, statistics, and underhook weighing.
