Product Code




The A&D ION BM-5 micro balances are designed for repeatable and reliable measurements in areas where accuracy is key. The balances feature a built in ioniser to remove charge from samples before measuring. This helps to ensure an accurate result, and quicker stabilisation. Integrated internal calibration ensures accurate readings. Further, the balance automatically recalibrates when changes in ambient temperature are detected.

Choose the best micro balance for your needs:

Weighing capacity: 5.2g
Readability: 0.001 mg (1μg)
