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!
