BM-500 Series Analytical Balance - 520g x .1mg

The BM-500 Ion Series Analytical Balance features anti-static glass, an internal calibration weight, and innovative static eliminator. With multiple weighing units and automatic or manual calibration, the Ion Series (BM Series) Analytical Balance is easy to use and maintain.
Weighing is at the heart of many laboratory processes and the Ion Series offers the features, performance and standard accessories to bring real convenience to your lab. With the six balances of the Ion Series, you can choose a capacity as high as 520 g or a microbalance with readability down to 1 µg. Critical to precision weighing is static control, which is why the direct current fanless ionizer is standard on all models. The automatic response adjustment function uses environmental data from built-in sensors to compensate the balance’s characteristics to deliver fast and stable results. Calibration is also automatic and always available with a single key press.
