A&D Weighing Gemini GR-300 Analytical Balance, 310 g, 0.1 mg

Features The A&D Weighing Gemini GR-300 Analytical Balance, 310 g, 0.1 mg, is crafted for precision and ease of use, equipped with advanced features tailored to meet the demands of diverse laboratory environments. Its splash and dust-proof membrane keypad, along with a robust die-cast aluminum base, provides durability and stability. The built-in internal calibration weight enables automatic self-calibration, ensuring consistent accuracy. A large 0.7-inch LCD display and straightforward six-button keypad interface make the balance easy to read and operate, while the front-mounted spirit level bubble helps users quickly achieve accurate leveling.

With an anti-static breeze break and ABS housing, along with stainless steel components such as the pan, spill ring, and base floor, the Gemini GR-300 is designed for easy maintenance and long-lasting performance. The compact footprint and collapsible doors save valuable bench space and reduce accidental mishaps, while easy-click door lock joints allow users to adjust the chamber for convenient access and workflow efficiency. The Full Digital Calibration function supports both internal and external calibration, allowing quick, reliable calibration on site for peak performance.

For data management, this model includes a memory function to store up to 200 weighing data records and complies with GLP/GMP/GCP/ISO output standards. Connectivity options include bi-directional RS-232C, and with the underhook for below-weighing applications, the Gemini GR-300 adapts to various tasks with precision. Supported by a 5-year warranty, this balance ensures reliable performance for your lab’s most critical measurements.
