- Counting uniform components and percent comparison
Calibration & Connections
Level the balance, allow at least one hour of warm-up and calibrate after moving it. Choose calibration weights suited to your measurement requirements.
The 51 g fine range includes any container mass. A tare above that limit prevents selection of 0.01 mg readability. Fit the fine-range breeze-break ring and minimize drafts, vibration and static.
A&D WinCT software supports compatible Windows computers. USB or Ethernet use requires the appropriate separate interface or converter.
Manuals & Accessories
Optional accessories include the AD-1653 density kit, AD-1688 data logger, AD-8526 serial/Ethernet converter, compatible 9-pin serial/USB converter and AD-1682 external rechargeable battery pack. Confirm compatibility and availability before ordering.
GLP/GMP-compatible output supports record keeping; it is not a calibration certificate or legal-for-trade approval.
