A&D Scale PN GR-300

A&D Scale PN GR-300 is a professional analytical balance with internal automatic calibration designed to deliver high-precision weighing performance for laboratories, pharmaceutical facilities, research institutions, chemical analysis, quality control departments, cannabis testing operations, and other applications requiring accurate measurement at the 0.1 mg level. As part of A&D’s Gemini GR Series, the GR-300 features a 310 g capacity with 0.0001 g (0.1 mg) readability, providing the sensitivity needed for analytical chemistry, sample preparation, formulation, pharmaceutical research, quality assurance, and precision laboratory weighing. A&D’s official specifications list 0.2 mg repeatability and ±0.3 mg linearity for the GR-300.

Designed for precision-focused laboratory environments, the A&D GR-300 features an Ø85 mm weighing pan enclosed within a glass draft shield that helps minimize measurement errors caused by air currents and environmental disturbances. The balance combines a relatively high 310 g maximum capacity with fine 0.1 mg readability, making it well suited for laboratories that need analytical-level resolution without sacrificing weighing capacity. Its compact, ergonomic design provides convenient access to the weighing chamber while helping conserve valuable laboratory bench space.

The GR-300 includes a built-in calibration weight and Automatic Self Calibration, allowing the balance to perform calibration using its internal mass when environmental conditions require adjustment. This helps maintain dependable weighing accuracy as ambient temperature changes and reduces the need to handle external calibration weights during routine operation. The balance also supports one-touch calibration and calibration verification procedures, making it a practical solution for laboratories where consistent measurement performance is essential.

The A&D GR-300 is engineered for efficient laboratory workflows with features such as data memory, under-hook weighing capability, a splash- and dust-resistant membrane keypad, and an easy-to-clean weighing chamber. The stable die-cast aluminum base helps provide a solid foundation for sensitive analytical measurements, while the enclosed draft shield protects the weighing area from environmental influences. Data memory capabilities allow the balance to store weighing results for applications requiring measurement tracking and organized data collection.

Standard RS-232C communication enables the GR-300 to integrate with compatible computers, printers, and laboratory data systems for weighing data collection and documentation. Combined with its internal calibration system, high-resolution weighing performance, enclosed weighing chamber, and versatile laboratory functions, the GR-300 provides a dependable platform for routine analytical weighing and precision measurement applications.

Whether you’re performing pharmaceutical research, chemical analysis, laboratory sample preparation, formulation, quality control, cannabis testing, precious material weighing, or scientific measurement, the A&D Scale PN GR-300 delivers the precision and flexibility required for demanding analytical applications. Its 310 g capacity, 0.0001 g (0.1 mg) readability, automatic internal calibration, Ø85 mm weighing pan, enclosed glass draft shield, data memory, and RS-232C connectivity make it an excellent solution for organizations requiring reliable analytical weighing performance.
