When selecting a digital analytical balance, the key specifications are readability (the smallest scale interval) and maximum weighing capacity; these should be matched to your specific weighing requirements:
0.1 mg (four-decimal-place) balance: Readability is 0.1 mg (0.0001 g) with a capacity typically ranging from 100 g to 320 g; suitable for high-precision applications such as chemical analysis and the preparation of micro-samples.
1 mg (three-decimal-place) balance: Readability is 1 mg (0.001 g) with a capacity ranging from 200 g to 2000 g; suitable for general laboratory sample weighing, jewelry weighing, and the inspection of small industrial components.
0.01 g (two-decimal-place) balance: Readability is 0.01 g with a larger capacity (e.g., 1 kg to 30 kg); commonly used for industrial counting, logistics weighing, baking, and other applications requiring relatively lower precision.
