Gemini GR-300 analytical balance has a 310 gram weighing capacity with sensitivity to 0.1 milligrams. Designed to meet the critical weighing needs in a variety of applications weighing procedures for the laboratory. It also requires 30% less footprint space.

Laboratory managers love the GR analytical laboratory balances and they're telling colleagues resulting in explosive growth of our company and the A&D line. Selling more allows Precision Weighing Balances to lower the cost to the end users. People are thinking - is that made in Switzerland balance really worth the difference in price? Have you every called that other manufacturer and all the want you to do is sign a service contract? Not with AND Weighing balances.

A&D has perfected the analytical balance with the introduction of the GR Series. Innovative design will continue to serve your weighing requirements for years to come. Flexible to meet almost any of your high precision weighing needs with the added versatility of built-in applications including counting & percent weighing.

The A&D GR Series is your "Total Weighing Solution" offering internal motorized calibration, RS-232 interface and balance data communication software all packaged together for one low price. Other manufacturer's charge you $100's more for either their balance communication software or a third party software but not with the A&D GR Series. Purchase the GR Series and you can have a paperless documented trail using WinCT data acquisition software and your PC.

If your application, such as a clean room, limits your ability to a PC you can still achieve ISO/GLP compliant output available via the RS-232(standard with all GR-Series) using the optional AD8121B printer. Now you can achieve today's stringent traceable requirements.

The GR-Series features the easy access door system. The tall draft shield can accommodate even tall flasks up to 8.64 inches in height. A built-in motorized calibration weight for optimum accuracy is possible at any time with a press of a button.

High performance and quality is shown with a 5 year manufacturer warranty. The A&D GR Series is made in Japan and A&D Weighing has two facilities in the USA located in Georgia and California if your balance ever needed repair.
