A&D Weighing ION BM-300 Analytical Balance, 320 g, 0.1 mg

Features The A&D Weighing ION BM-300 Analytical Balance offers exceptional precision with a capacity of 320 g and readability of 0.1 mg. It features a built-in fan-less ionizer that neutralizes electrostatic charges instantly, enhancing accuracy without additional costs. The balance's large breeze chamber accommodates various sample vessels, while anti-static glass coating shields against external electrical interferences. Users can tailor response times with automatic or manual stabilization settings (FAST, MID, SLOW) based on environmental disturbances. Integrated sensors continuously track and display temperature, humidity, and atmospheric pressure to maintain optimal conditions.

This balance also includes an illuminated spirit level for quick leveling, enhancing accuracy and precision. With one-touch Full Digital Calibration and Auto Self Calibration, it adapts to onsite conditions and ambient temperature changes, ensuring consistent performance. The balance stores up to 200 data points and supports GLP/GMP/GCP/ISO compliant reporting, which includes detailed records such as manufacturer, model, and serial number, alongside calibration and audit details.

Additional functionalities include a reverse liquid crystal display, percent weighing, piece counting, and an underhook feature for below-balance weighing. Connectivity options include a standard USB and RS-232C interface, with optional Bluetooth and LAN Ethernet connections via WinCT-Plus software. The AD1688 Data Logger complements this setup by storing up to 5,000 points with time/date stamps for comprehensive data management. A 5-year US warranty guarantees long-term reliability, making the ION BM-300 a superior choice for precise analytical tasks.
