Laboratory semi-microbalance BM-S

electronicanalyticalmg

Overview
BM-S Series standard-level semi-micro balances providing 0.01 mg readability (with smart range function) and integrated conveniences for reliable semi-micro weighing. Key design items include an internal weight for automatic self-sensitivity adjustment (AD-Just), anti-static glass breeze break with transparent evaporated metal coating, two breeze break rings (including a high-profile ring for better draft protection), and selectable response characteristics to suit location drafts and vibrations.
