A&D Ion BM Series Analytical & Microbalances eliminate interference with easy ION switch – allows built-in fanless internal ionizer to neutralize electrostatically charged objects instantly at no additional costs. It’s large breeze chamber is flexible enough to allow all sample vessels, small or large. The anti-static glass coating blocks outside electoral interferences and the built-in environmental sensors monitor and displays the temperature, humidity, and atmospheric pressure. 

These balances feature superior functionality with illuminated, back-mounted spirit level bubble to help reduce leveling time and increase accuracy and precision. One-touch Full Digital Calibration ensures balance is calibrated onsite for the best performance. The auto self-calibration will detect changes in ambient temperature and auto calibrate.

Key Features

  • Enhanced OES Ordinal Electromagnetic Sensor with Micro 0.001mg resolution
  • Anti-static glass breeze break with a thin evaporated metal coating
  • Adjustable (manual or automatic) response characteristics to help cope with the effect of drafts and vibrations
  • Automatic self-calibration to maintain accuracy under temperature changes
  • Embedded temperature, humidity and atmospheric pressure sensors
  • Multiple weighing units: g, mg, oz, ozt, ct, mom, dwt, grain, specific gravity
  • Comes equipped with the handy AD-1688 weighing data logger
  • GLP/GMP/GCP/ISO compliant output
  • Counting mode with the Automatic Counting Accuracy Improvement (ACAI) function
  • Percent mode function
  • Comparator function with buzzer
  • Underhook function
  • Special pans/holder (BM-20/22)
  • Density determination function and an optional density determination kit (for BM-252/200/300/500 only)
  • RS-232C and Quick USB interfaces as standard
