Sub-microgram weighing without the static drift. The A&D BM Series Ion Micro Analytical Balances weigh down to 0.001 mg (1 µg) with a built-in fanless ionizer that neutralizes static on samples, weigh boats, and glassware in seconds — eliminating the single largest source of error in micro-weighing. Capacities from 5 g to 520 g cover everything from USP <41> minimum-weight work to standard analytical weighing.

Standard on every model: motorized internal calibration, Super Hybrid Sensor, RS-232C + Quick USB, GLP/GMP/ISO-compliant output, password protection for up to 11 users, and 21 CFR Part 11 bidirectional command set.

Why Prime USA Scales: Authorized A&D Weighing dealer, 5-year warranty, free shipping to the lower 48, and expert pre- and post-sale support. Not sure which BM fits your minimum weighing requirement? Call 800-711-2237 and we will size the right model to your application before it ships.

Features:

Eliminates Interferences

  • Easy ION switch allows built-in fan-less internal ionizer to neutralize electrostatically charged objects instantly at no additional costs
  • Large breeze chamber is flexible enough to adjust to all sample vessels small or large
  • Anti-static glass coating blocks outside electrical interferences
  • Auto response adjustment allows balance to auto or manually stabilize FAST, MID, SLOW depending on draft &vibration influences
  • Built in environmental sensors monitor and display the temperature, humidity and atmospheric pressure

Superior Functionality

  • Illuminated back-mounted spirit level bubble helps reduce leveling time and increase accuracy & precision
  • One touch Full Digital Calibration (internal & external) ensures balance is calibrated onsite for the best performance
  • Auto Self Calibration will detect changes in ambient temperature and auto calibrate.
