A precision balance is an accurate, robust weighing instrument with capacities from 120 g to 64 kg, and readabilities from 1 g to 0.1 mg. Lower readability models have a draft shield to ensure the best performance, while high-capacity models have a large weighing pan to accommodate heavy loads. Precision balances are used in a variety of applications in the lab and in manufacturing environments, including sample and standard preparation, formulation, statistical quality control, and counting.
