2 set 1770 ano - Precision Balance
Descrição:
(could weigh objects to nearest 0.0005g)
3000 BCE, in order to establish a cost to all the goods that could not have been counted per unit, led to the Egyptians to create an instrument that was capable of completing this task. This system eventually would be built upon by later generations of Egyptians, Europeans, etc. There are differing types of precision balances, such as the Spring balance, the weighing platform or Roman, the analytical balance, the counterbalance, or the medical balance. The first balance that did not use counter weights was invented in 1770 by Richard Salter
