Timbangan Micro balance AND GF-224A

GF-224A Analytical Balance

The GF-224A Analytical Balance from the advanced Apollo series delivers exceptional precision and intelligent protection for high-demand laboratory applications. Designed for professional environments, this balance offers a weighing capacity of 220 grams with a high readability of 0.1 milligram (0.0001 g) and a 90 mm pan diameter, making it ideal for sensitive weighing tasks in research, pharmaceutical, and industrial settings.

At the heart of the GF-224A is A&D’s Smart Super Hybrid Sensor (Smart-SHS), an advanced weighing mechanism that ensures fast stabilization—typically 1.5 to 2 seconds—while maintaining outstanding accuracy. This significantly boosts productivity without sacrificing performance.

The balance features external calibration, allowing users to manually calibrate the unit using certified test weights for maximum control over measurement accuracy. It also complies with GLP, GMP, and GCP standards, offering traceable data with manufacturer details, serial numbers, user IDs, timestamps, and calibration records.

For enhanced workflow efficiency and safety, the GF-224A includes advanced features such as Impact Shock Detection (ISD), which provides visual and audible alerts when the instrument experiences physical shock, and Flow Rate Display (FRD), which improves the precision of liquid dispensing or sample transfer. Password protection supports up to 11 users and 1 administrator, safeguarding settings in shared lab environments.
