The Class A balance should be used for all the weighing operations required in prescription compounding.One may also ask, what is maximum sensitivity of a torsion balance? According to Newton’s report, the sensitivity of torsion balances are 0.006g, and the smallest readable amount is 0.01g, whereas electronic balances can range from 0.01g to 0.002g.
