Introducing our innovative micro balance! Accurate measurement for precision weighing with micrograms readability.

How to Eliminate the Greatest Enemy of Precision Weighing 

Static electricity, while often overlooked, can be a fatal source of error in precise weight measurements. With the BM Series, A&D seek in various ways to help you perform sometimes-tricky analytical weighing with simplicity and accuracy,
including the elimination of static electricity. The world of micro grams (µg) is now accessible to all researchers!

Built-in Fanless Ionizer

The internal ionizer neutralizes an electrostatically charged object instantly. Simply hold the sample in the neutralizing chamber for a second before placing it in the weighing chamber.

Anti-static Breeze Break

The thin evaporated metal coating of the breeze break blocks outside static electricity.

Motor-driven Internal Calibration Mass

The internal mass of the BM Series allows you to perform calibration quickly and correctly even if you are not skilled at calibrating balances using external masses.

Large Weighing Chamber for Improved Usability

To block drafts, A&D adopted a double-ring structure around the weighing pan and two vertical shields under the separation plate. This offers more space and easier operation than conventional 1 µg balances with a secondary breeze break in the chamber.
