A&D – Analytical Balances – BM / GR Series
Static electricity, while often overlooked, can be a fatal source of error in precise weight measurements. With the BM and GR 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!
A unique system allows the user to conveniently open or close the left or right side of the weighing chamber using a control lever.
Key Features
BM Series
- A built-in fanless ionizer that allows for instant removal of destabilizing static electricity from the sample and container
- Includes four 0.001 mg readability models to be selected for different purposes
- Comes equipped with the AD-1676 tabletop breeze break (medium) as standard (BM-5/5D/20/22)
GR Series
- Semi-micro, 0.01 mg readability up to 42 g (GR-202)
- Handy lever on the front to open either side of the weighing chamber for quick and efficient access
- Small footprint of 249 mm by 330 mm to save space
