Easy, fanless static elimination using a built-in ionizer
Better operability with a large weighing chamber
Interlockable slide doors allowing efficient operation with both hands
Automatic calibration with an internal mass
Clearly visible, white-backlit LCD
Built-in temperature, humidity, and atmospheric pressure sensors
RS-232C and Quick USB interfaces as standard
AD-1688 weighing data logger as a standard accessory
Special pans/holder available for elemental analyses, PM filters, and microfuge tubes (BM-20/22)
Optional pipette accuracy testing kit (BM-20/22)
