Replaces the discontinued A&D GF-300N.
Replaces the A&D GF-300P. A&D has discontinued the GF-300P; the A&D GF-303AN is the closest current model, with 0.001 g readability, NTEP Class II approval (e = 0.01 g), external calibration, and the same 128 × 128 mm pan as the GF-300P, plus more capacity (320 g vs. 310 g), USB, impact shock detection, and password protection.
The A&D Weighing GF-303AN Precision Balance provides 320 g (NTEP) capacity, 0.001 g (NTEP 0.01 g) readability, 5 x 5" (128 x 128mm) platform or pan, NTEP approval. It is suited to laboratory weighing, manufacturing quality control, formulation and sample preparation.

Description
A&D GF-303AN Precision Balance 320gX0.001g NTEP
The A&D Weighing GF-303AN Precision Balance is a professional precision balance offering a 320 g (NTEP) capacity, 0.001 g (NTEP 0.01 g) readability, an NTEP-approved configuration. It is suited to laboratory weighing, manufacturing quality control, formulation and sample preparation and other applications that require reliable, repeatable weighing.
Replaces the A&D GF-300N
The A&D GF-303AN replaces the A&D GF-300N (310 g × 0.001 g, NTEP), which A&D has discontinued. It keeps 0.001 g readability and NTEP Class II approval and adds capacity, USB, and impact shock detection.
Replaces the A&D GF-300P
A&D has discontinued the GF-P series. If you are looking for an A&D GF-300P, or replacing one, the GF-303AN is the closest current A&D model, with 0.001 g readability, NTEP Class II approval (e = 0.01 g), external calibration, and the same 128 × 128 mm pan as the GF-300P, plus more capacity (320 g vs. 310 g), USB, impact shock detection, and password protection. See the A&D GF-300P reference page for the old specs, or call us at (832) 290-3120.
