A&D Weighing GX-4002AN Apollo Precision Balance with Internal Calibration, NTEP, 4200 g x 0.01 g

Yes. The GX-4002AN is an NTEP Class II approved precision balance designed for applications where legal-for-trade weighing is required. It provides 0.01 g displayed readability, while its approved verification interval (e) is 0.1 g. This makes it a strong choice for businesses that need precise measurements along with an approved instrument for commercial transactions. Local weights-and-measures requirements still apply before placing the balance into legal-for-trade service.

The GX-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 while working with comparatively large samples. It offers 0.01 g repeatability and ±0.02 g linearity, making it well suited for formulation, quality control, production, batching, inventory, and other precision-weighing applications.

Yes. The GX-4002AN features A&D's automatic internal calibration (ASC) system. Because the calibration weight is built into the balance, routine sensitivity adjustment can be performed without manually placing an external calibration weight on the pan. This is particularly convenient for laboratories and quality-controlled environments where maintaining consistent weighing performance is important.

The GX-4002AN is designed for fast precision weighing, with approximately 1-second stabilization in FAST mode under suitable conditions. A&D also specifies approximately 0.8-second stabilization with a 50 g load for this model group. Faster stabilization can improve productivity when operators perform numerous measurements throughout the day.

Yes. The GX-4002AN provides USB and RS-232C communication interfaces, allowing weighing results to be transferred to compatible computers and other data-recording equipment. This can reduce manual transcription and improve traceability in laboratory, production, and quality-control workflows. The balance also supports applications such as parts counting, percentage weighing, animal/dynamic weighing, density determination, statistics, and underhook weighing.
