Frequently Asked Questions

What are the capacity and readability of the A&D GF-303A?

The A&D GF-303A has a maximum weighing capacity of 320 g with 0.001 g (1 mg) readability. A&D specifies 0.001 g repeatability and ±0.002 g linearity, making it suitable for laboratory testing, formulation, sample preparation, quality control, research, and other applications requiring precise milligram-level measurements.

Does the A&D GF-303A use internal or external calibration?

The GF-303A uses external calibration, meaning users calibrate the balance with an appropriate external reference weight rather than relying on a built-in calibration mass. This makes it a practical option for laboratories and quality-control facilities that already maintain certified or traceable calibration weights.

How quickly does the A&D GF-303A stabilize?

The GF-303A is designed for fast precision weighing. A&D specifies an approximate 1-second stabilization time in FAST mode under good environmental conditions, and approximately 0.8 seconds for a 5 g load. This quick response can help improve productivity during repetitive weighing procedures.

Can the A&D GF-303A be used for parts counting and percentage weighing?

Yes. The GF-303A supports several weighing modes, including parts counting and percentage weighing. Its counting function supports sample quantities of 5, 10, 25, 50, or 100 pieces, while percentage mode can be used to compare a sample against a stored reference mass. These functions make the balance useful beyond basic laboratory weighing.

What is the difference between the A&D GF-303A and GX-303A?

Both models provide 320 g capacity, 0.001 g readability, 0.001 g repeatability, and ±0.002 g linearity. The main difference is calibration: the GF-303A uses external calibration, while the GX-303A includes a built-in calibration weight for internal calibration. The GF-303A is therefore a good choice for users who already maintain external calibration weights, while the GX-303A is more convenient when built-in calibration is preferred.
