【Abstract】 An instrument was designed and made to measure tiny mass within the range from 100 mg ~ 500 mg.That measurement is based on Archimedes Law and its precision achieves 2mg. The measurement instrument has some advantages,such as simple principle,mechanical structure design and low costs. This instrument presents a new method for tiny mass measurement.更多还原
