A&D BM Microbalance
Starting From: £3,236.00

Highest level of weighing precision available. Ideal for measuring hazardous chemicals and pharmaceutical production.

Exceptional-quality microbalance manufactured by A&D, the BM series includes all the features and functions expected of a premium balance including parts counting, percentage weighing and density determination. Inter-lockable sliding doors allowing efficient operation with both hands, whilst a built-in fan-less ionizer combined with anti-static glass breeze break and a thin evaporated metal coating ensures weighing stability and eliminates static build up inside the weighing chamber.

The BM microbalance offers an impressive selection of weighing units outside for the usual gram, kilogram and microgram measurements including carat, momme, grain and troy ounce, with taels available on request.

Static electricity, while often overlooked, can be a fatal source of error in precise weight measurements. With the BM micro analytical balance series, A&D seek 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!

What do the 100g x 1mg type numbers mean?

When we show pairs of numbers such as 100g X 1mg or 12kg x 0.1g we are using an industry-wide shorthand which represents: capacity x readability. The 'x' does not mean multiply but could be read as 'with'.

Capacity is the maximum mass that can be measured on that scale or balance.

Readability is the smallest difference that the scale or balance can weigh to and display. Readability can be also be referred to as graduations, precision and resolution.
