what instrument is used to measure mass

The instrument used to measure mass is typically a balance or a scale. Balances and scales work by applying an equal and opposing downward force on both sides of the device, directly measuring mass. There are different types of balances, including beam balances, top pan balances, and electronic balances. In addition to balances and scales, other tools used to measure mass include measurement transducers, vibrating tube sensors, and Newtonian mass measurement devices. It is important to note that mass and weight are not the same thing, and instruments used to measure weight, such as spring balances, do not measure mass accurately.
